The test and calibration of audio-frequency circuits and systems often require a sine wave with an accurate amplitude and frequency and a ... between the synchronization-tracking speed (or maximum ...

In order to perform this harmonic reduction, a pure sine wave must first be applied to the Class-D amplifier ... The output signal was captured and analyzed in Matlab for the amplitude and phase angle ...

The circuit creates a closed-loop system that supplies a fixed and adjustable peak-to-peak amplitude ac signal centered around 0 V. A 1-kHz sine wave, labeled AC_INPUT, is The figure shows a ...
