Abstract
Official abstract text for this publication.
A de-pop controller and method thereof are provided. The controller includes an amplifier and a comparator. The amplifier receives and amplifies an audio input signal, and then outputs an audio output signal. The comparator, coupled to the amplifier, receives a transient indication signal. The comparator compares the transient indication signal with a reference voltage, and the comparison result is then applied to control the driving ability of the amplifier for de-popping.
First claim
Opening claim text (preview).
What is claimed is: 1. A de-pop controller, comprising: an amplifier that receives an audio input signal and amplifies the audio input signal to output an audio output signal; a comparator, coupled to the amplifier, that receives a transient indication signal and compares the transient indication signal with a reference voltage to generate a comparison signal that controls a driving ability of the amplifier; and a timing control circuit that generates the transient indication…
