What is amplitude of signal

"The amplitude of a signal measures the value of the signal at any point. The frequency of a signal refers to the number of periods in one second. The phase describes the position of the waveform relative to time zero."

What's the amplitude of signal?

Signal strength or amplitude is measured by the distance of each curve from the zero axis (or red (black in print versions) line in the figure). The direct signal is very much stronger than those of the target area.

What is amplitude in signal and system?

The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the variable's extreme values.

What is the amplitude?

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.

What is amplitude in analog signal?

The amplitude of an analog signal source is measured in volts, and the frequency of an analog signal is measured in Hertz. The unit for a sine wave's peak-to-peak voltage amplitude is called the volt.
