4. Can peak amplitude be negative?

What is the amplitude of FFT?

The amplitude of the FFT is related to the number of points in the time-domain signal. Use the following equations to compute the amplitude and phase versus frequency from the FFT. where the arctangent function returns values of phase between -π and +π, a full range of 2π radians.

How do you find peak to peak amplitude?

Peak-to-peak (pk-pk) is the difference between the highest and the lowest values in a waveform. In alternating current (AC) the peak-to-peak value is twice the peak value or 2.828 times the root-mean-square (RMS) value.

What is the peak amplitude?

The peak amplitude of a sinusoidal waveform is the maximum positive or negative deviation of a waveform from its zero reference level.

Can peak amplitude be negative?

The amplitude or peak amplitude of a wave or vibration is a measure of deviation from its central value. Amplitudes are always positive numbers (for example: 3.5, 1, 120) and are never negative (for example: -3.5, -1, -120).
