<p>Techniques for applying waveform shaping to DC to DC level transitions in an audio amplifier. In an aspect a waveform shaping block may utilize a non linear shaping waveform such as a Gaussian waveform raised cosine waveform root raised cosine waveform etc. to shape the transition between two DC levels in an audio amplifier output. The waveform shaping techniques may be utilized e.g. during power up or power down of the amplifier or in an impedance measurement mode to reduce audio artifacts associated with the transition while minimizing overall transition time.</p> |
