Multi channel audio signal converting device using time varying digital filter Electronic system including the same and Method for converting audio signal of multi channel

摘要

A multi-channel audio signal conversion apparatus using a digital time-varying filter, an electronic system including the same, and a multi-channel audio signal conversion method dl using a digital time-varying filter. Embodiments of the present invention include first and second signal channels each performing an analog-to-digital conversion or a digital-to-analog conversion using a first clock signal; And a digital audio signal synchronized with a second clock signal different from the first clock signal is input to the second signal channel in synchronization with the first clock signal, And a first time-varying filter for outputting in synchronization with the clock signal, thereby resampling the asynchronous audio signal to synchronize all the analog circuits, thereby eliminating the interference between the asynchronous clock signals.
