Audio Amplifiers

Class D amplifiers use a switching process that adds fast-rising edges at the switching frequency to the audio output signal, presenting a difficult signal for audio analysis. The solution is to precondition the signal before presentation to the analyzer using a low-pass filter that reduces the out-of-band switching components (the fast edges) ...more
