Question

What is the peak amplitude of a sinusoidal signal?

Answer 1

Amplitude. The AMPLITUDE of a sine wave is the maximumvertical distance reached, in either direction from the centre line of the wave. As a sine waveis symmetrical about its centre line, the amplitude of the wave is half the peak to peak value

Answer 2

Answer:

The peak amplitude of a sinusoidal waveform is the maximum positive or negative deviation of a waveform from its zero reference level. ... If the positive peak has a value of 10 volts, then the negative peak will also have a value of 10 volts.
