Wave that has been reflected or otherwise returned with sufficient magnitude and delay for it to be perceived as a wave distinct from that directly transmitted.
Signal that has been reflected or returned as a result of impedance mismatches, hybrid unbalance, or time delay. Depending upon the impedance irregularities and the propagation characteristics of a facility, echo may interfere with the speaker or listener, or both.

A signal that has been reflected or otherwise returned with sufficient magnitude and delay to be perceived by the speaker.
the Roman version of the myth of Echo was written by Ovid who said Echo was a nymph assigned by Zeus to talk incessantly to Hera distracting her from Zeus amorous affairs with mortals and gods; Hera discovered the ruse and punished Echo by making her repeat what others said; Echo fell in love with the mortal Narcissus whose vanity caused him to stare at his reflection in a pool of water until he died; overcome with grief, Echo pined for her lost love and faded away leaving only her voice behind to echo the voices of others; the Greek version of the myth of Echo says that Echo was a musical nymph who could sing and play many instruments; her musical skills attracted the jealousy and hatred of many including the god Pan; Pan had his shepherds kill Echo and tear her apart scattering her pieces; the goddess Gaia (mother earth) took the pieces of Echo into her bosom; Echo's voice and talents were thus scattered all over the earth and that is why she is heard imitating sounds and voices in all corners of the world.
The resulting sound when Pam does not turn down her speaker.
A distortion that occurs when a signal is reflected or otherwise returned (on the same wire on which the speaker is speaking) with sufficient magnitude and delay as to be perceived by the speaker. [Typically, a problem on satellite circuits.
A signal sent back to the originating device for display or verification.
In telephony, because of impedance irregularities in the terminating networks, a small amount of energy transmitted in one direction over the switched network is often reflected at the receiving end back toward the originating end. This reflection is commonly referred to as “talker echo.” A second echo at the receiving end is called a “listener echo,” or singing.
The reflection of the original sound wave as it bounces off a distant surface. The RF signal reflected back from a radar target.
1. A sound reflected off a surface that arrives at the listener after the direct sound. Sometimes thought of as reverberation, but an echo is very distinct while reverberation is a mixed together sound which decays gradually. 2. An effect produced by a signal processor to achieve the results in number 1, above. 3. A control (signal path) on a mixer used to send part of the signal to a signal processor which creates the desired echo effect. (Very similar to a post-fade auxiliary control.)
A wave which has been reflected at one or more points in the transmission medium. Echoes may be leading or lagging the primary signal and appear in the picture monitor as reflections or double images commonly called "ghosts."

(v.) To repeat a stream of characters. For example, the commands the user types are echoed on the screen.
The repetition on the screen of characters typed in via the keyboard.
A reflected sound that arrives after a delay sufficient for a listener to distinguish it as a discrete event in time. In rooms this is modified by the reverberation time of the space. ECL - Emitter Coupled Logic A family of high speed, low power IC logic devices. Also called "Current Mode Logic".
A wave which has been reflected at one or more points in the transmission medium, with sufficient magnitude and time difference to be perceived in some manner as a wave distinct from that of the main or primary transmission. Echoes may be either leading or lagging the primary wave and appear on the picture monitor as reflections or "ghosts."
Delay, repeat, and vocal reverberations to enhance vocals.
The combined effect of a sound and a delayed version of that same sound. A 'Slap-Back Echo' is the original sound plus a single repeat; "Multiple Echo" is the original sound plus several repeats with the same delay spacing.
An audio effect which is similar to the acoustic effect "Hall". Everybody is familiar with the effect, which also occurs when you shout something from the top of a mountain into a valley and it is reflected back to you.
1. n. In computer graphics, the immediate notification of the current values provided by an input device to the operator at the display console. 2. n. In word processing, to print or display each character or line as it is keyed in. 3. n. In data communication, a reflected signal on a communications channel.
a reflection of sound that is delayed long enough to be heard as a distinct repetition of the original sound (usually more than about 50 milliseconds.)
(1.) A reflected signal on a communications channel. On a communications terminal, each signal is displayed twice, once when entered at the local terminal and again when returned over the communications link. This allows the signals to be checked for accuracy. (2.) In computer graphics, the immediate notification of the current values provided by an input device to the operator at the display console. (3.) In word processing, to print or display each character or line as it is typed in.
A discrete repetition of a sound, as opposed to reverberation, which is a continuous wash of closely spaced, non-discrete echoing sound. See delay (3), reverb.
The reflection of a portion of a signal back to its source.
SUPPRESSOR/ECHO CANCELLER These are active devices used by the phone company to suppress positive feedback (singing) on the phone network. They work by predicting and subtracting a locally generated replica of the echo based on the signal propagating in the forward direction. Modems deactivate these devices by sending the 2100Hz answer tone with 180 phase reversals every 450msec at the beginning of the connection.
A voice enhancing effect which provides a close echo of your voice as you sing. This gives a more professional sound, and obscures some mistakes and tuning problems for poor singers.
The energy return of a radar signal after it has hit the target. Also called a radar echo.
The component of an analog device's receive signal reflected into the analog device's transmit signal.
the effect of a sound reflecting off a distant surface and returning to the source. Typically, an echo is defined as a delay lasting more than 50 milliseconds (0.05 seconds).
the repetition of a sound delayed in time by at least 50 milliseconds after the original. An effect often found in synthesizers and samplers.
Reflection of sound that is delayed long enough (more than about 50 msec.) to be heard as a distinct repetition of the original sound.
A very basic effect produced by repeating a sound with a delay long enough to be heard as a separate event. It is often just called Delay and is usually used to add more depth to an audio signal without the muddiness often introduced by Reverb.
A signal which has been reflected with sufficient magnitude and delay for it to be perceptible. The round trip propagation delay between two earth stations is 500 to 600 milliseconds and being remedied by the use of echo cancellers.
Distinct repetition of a sound until it dies away naturally. Distinct or indistinct repetition of a sound produced and controlled in the studio for effect, mechanically or by means of electronic processors. See delay, DDL, analogue delay.

(Echocardiogram) - A heart test done with sound waves to pick up the image of the heart and its vessels through the chest wall without hurting the baby.
A signal which has been reflected at one or more points during transmission with sufficient magnitude and time difference as to by detected as a signal distinct from that of the primary signal. Echoes can be either leading or lagging the primary signal and appear as reflection, or "ghosts" in an AM system.
A signal indicating reflected acoustic energy.
The reflection of sound waves that results when they bounce off an object such as a window or wall. Reflected signals sound like a distorted and attenuated version of the talker's speech. Echoes in telephone and videoconferencing applications are caused by impedance mismatches: points where energy levels are not equal.
These are reverberation artifacts so spread out in time (especially the initial reflection) that the reflected signal is perceived as a distinct sound. A distinct echo is usually not desirable, unless a recording was made in a reverberant space, such as a very large church.
The distortion or noise, which can be delayed in time, that is reflected back to the sending or originating station.
In radar, a general term for the appearance, on a radar display, of the radio signal scattered or reflected from a target. The characteristics of a radar echo are determined by 1) the waveform, frequency, and power of the incident wave; 2) the range and velocity of the target with respect to the radar; and 3) the size, shape, and composition of the target. See also target signal, blip.
In audio signal processing and acoustics, an echo (plural echoes) is a reflection of sound, arriving at the listener some time after the direct sound. Typical examples are the echo produced by the bottom of a well, by a building, or in a room, by the walls. A true echo is a single reflection of the sound source.
