【発明の名称】マルチチャネル信号処理の方法および装置
Document Type and Number:
Japanese Patent JP2003510973
Kind Code:
A
Abstract:
A multiple channel signal processing circuit receives an input associated with a first channel and an input associated with a second channel. The respective inputs are sampled and processed by the circuit, which generates a sampled output signal for the first channel and a sampled output signal for the second channel. The circuit employs a shared active circuit component, such as an operational amplifier, to alternately process samples associated with the first and second channels. A network of switches are controlled by a multiphase clock signal such that the active circuit component processes samples associated with only one channel at a time; as the input for a first channel is being sampled, a previous sample for the second channel is processed. An alternate circuit embodiment may be utilized to reduce the amount of crosstalk between the channels.
