- Click and Pop Measurement TechniquePDF, 263 Kb, File published: Apr 1, 2005
During various occasions a digital amplifier can generate a click or a pop. The click is generated at changes of the operational modes of the amplifier, e.g., charging ofcapacitors or mute/unmute. For Class D amplifier systems, click is typically at PWM start and stop. The audibility of a click depends on the system, amplifier, and speaker. Also, perception of the click is subjective.

Selecting the optimal power supply for a non feed back digital amplifier can bechallenging. Music is dynamic, so the power consumption is changing dramatically,from almost zero to maximum within a few ms.Designing the power supply so powerful that it can deliver the total amplifier outputpower continuously is too costly and usually unnecessary.Designing the power supply too small gives p - PSRR for Purepath Digital Audio AmplifiersPDF, 159 Kb, File published: Apr 15, 2005
