a representation of how alternating current (AC) varies with time
a 2-D graph of one period of a signal, showing changes in pressure (amplitude) as a function of time.
The waveform of a signal is a graph of its instantaneous voltages versus time. In audio, for example, we are always dealing with periodic waveforms that make up what we hear. These periodic waveforms can be plotted on a graph and will show up as some type of squiggly (how's that for a word?) line. From left to right is time (usually a very short slice of time) and from top to bottom is the amplitude of the sound (or relative voltage) at those instants in time. The familiar sine wave is an example of this. Waveforms, or Waves (a Wave File, for example) are also the names sometimes given to samples or snippets of sound that are used in various electronic sound generating or playing instruments. The usage of the word comes from the definition above and has become commonplace in the modern day era of audio production where one is often looking at waveforms on a computer screen while editing sounds.
A picture of vibration as it proceeds through time. Term found in About the Voice: Acoustics 101.
the record of a signal that varies over time. A blood flow signal usually varies periodically with the cardiac cycle.
ˈwevˌfɔɹm] - a diagram of the vibrations of a wave, with time shown on the horizontal axis and pressure variation or amplitude on the vertical axis.
A graphic representation of a voltage varying over time.
The shape of a wave that represents a vibration or AC current.
The graphical shape of a wave.
A two-dimensional graph of a signal, showing changes in pressure (amplitude) as a function of time.
A graphical representation of a signal as a plot of amplitude versus time, i.e. the shape of a wave.
The graphical representation of a wave, showing variation of amplitude with time.
The shape of a wave or pattern representing a vibration. The shape characterizing an AC current or voltage output.
The shape of the electromagnetic pulse from a time-domain electromagnetic transmitter.
The geometric shape of one period of an electric signal when it is plotted or displayed versus time or some other variable.
The shape of a sound or electrical wave.
A graph showing the amplitude of a sound over a particular interval of time. Any portion of that interval is a sample.
the graphical display of a sound pressure wave over time.
The shape of a wave (a graph of a wave's amplitude over time).
The shape of the graphic representation of a sound wave.
A graphic representation of the shape of a sound wave. The waveform determines some of the physical characteristics of the sound.
the pattern of a sound wave or other electronic signal in analog form.
The characteristic shape of an AC current or voltage output.
The pictorial representation of the shape of a wave showing the amplitude variations as a function of time; a wave as it might be displayed on a cathode-ray tube.
A signal, either sampled (digitally recorded) or periodic, being generated by an oscillator. Also, the graphic representation of this signal, as on a computer screen. Each waveform has its own unique harmonic content. See oscillator.
The pattern of variations of voltage or current showing how the quantity changes with time.
A graphical representation of the rise and fall of the electrical potential (voltage) on a pair of wires or some other signal over time. A classic example of a waveform is the spiky line displayed on a cardio-graph machine used to analyze the electrical activity created as the heart beats. In telephony, analog waveforms are translated into a series of binary values, called samples. These samples are taken 8,000 times a second, sent on to their destination, where they are translated back into a series of 8,000 changes in voltage that almost resembles the original analog signal.
A display of a signal (on an oscilloscope) that shows the magnitude of current or voltage signal with respect to time. By displaying the waveform of a signal on an oscilloscope, the time between cycles can measured and its frequency can be calculated.
A waveform is the characteristic shape of a graphically displayed audio signal. - Category: Equipment and Gear
Waveform means the shape and form of a signal, such as a wave moving across the surface of water, or the vibration of a plucked string.
