A temporary change in voltage of any length
(1) A signal that can be wholly described by a constant amplitude and the duration time. (2) Signal form typically used internally in computers, terminals and other business machines as well as in communications facilities.
This occurs when either current or voltage changes abruptly in value for a finite length of time.
A short burst of electromagnetic energy that a radar sends out in a straight line to detect a precipitation target. The straight line that this pulse travels along is called a radar beam.
A very short duration of time. In regard to a radar, it is a brief burst of a electromagnetic radiation emitted by the radar.
Signal characterized by a steep rise from and decay toward an initial level.
produce or modulate (as electromagnetic waves) in the form of short bursts or pulses or cause an apparatus to produce pulses; "pulse waves"; "a transmitter pulsed by an electronic tube"
a function with unit energy and infinitesimal duration
a special waveform of only one or a few crests
a sudden voltage rise followed somewhat later by a sudden voltage drop
A brief and abrupt change in voltage and current produced by turning a SCR on and off in an SCR System.
A rise and fall of voltage, current, or other faction that would be constant under normal conditions. A pulse that is intentionally induced will have a finite duration time.
A short burst of electromagnetic radiation transmitted by a radar antenna.
a momentary, sharp change in a current, voltage, or other quantity that is normally constant. A pulse is characterised by a rise and a decay and has a finite duration. It also called impulse. a figure of merit for an energy-storing device, tuned circuit, or resonant system. It is equal to reactance divided by resistance. The Q of a capacitor, coil, circuit, or system thus determines the rate of decay of stored energy; the higher the Q, the longer it takes for the energy to be released. It is also called Q factor and quality factor.
An electrical signal or voltage of short duration. Typically used to describe the signals sent from the indexer to the driver.
Variation in electrical energy above or below a normal level and a given duration, such as a brief surge of voltage or current.
A momentary, sharp alteration in the current or voltage produced in a circuit to operate a switch or relay which can be detected by a logic circuit; a sharp rise and fall of finite duration.
A common waveform shape that has a fast rising edge, a width, and a fast falling edge.
A discontinuous burst of laser, light or energy, as opposed to a continuous beam. A single burst of energy from a laser. A true pulse achieves higher peak powers than that attainable in a CW output. See CW.
A type of waveform that consists of two equal and opposite steps in voltage or current separated by a time interval.
Rise and fall of some quantity (usually voltage) for a period of time.
A current or voltage that changes abruptly from one value to another and back to the original value in a finite length of time. Specifically, describes one particular variation in a series of wave motions. A pulse typically starts at 0 volts and rises to a maximum voltage, such as 3.5 or 5 volts. After remaining at the high, it falls to 0 volts. In digital transmissions, 0 volts equals binary 0 and 5 volts equals binary 1. An ideal pulse rises immediately from 0 volts to a maximum. In reality, pulses are irregular.
(1) A variation of a quantity whose value is normally constant; this variation is characterised by a rise and a decay, and has a finite duration. (2) A short burst of electromagnetic radiation transmitted by the radar.
A current or voltage which changes abruptly from one value to another and back to the original value in a finite length of time. Used to describe one particular variation in a series of wave motions. The parts of the pulse include the rise time, fall time, and pulse width, pulse amplitude. The period of a pulse refers to the amount of time between pulses.
In radar, sodar, or lidar a single short-duration transmission (or burst) of energy. A pulse is characterized by its radio frequency, pulse repetition frequency, pulse duration, and peak power.
