摘要：
A device for amplifying multiple signals includes a plurality of sensors, where a plurality of lead signals are dervied from the plurality of sensors, a plurality of low-pass filter and buffer amplifiers for filtering and buffering the plurality of lead signals, one or more multiplexers, where outputs from the plurality of low-pass filter and buffer amplifiers are input to one of the one or more multiplexers, a single amplifier channel, where the outputs of the one or more multiplexers are input to the single amplifier channel and a microcontroller which controls the one or more multiplexers, wherein the microcontroller stores software which selects, in sequence, one at a time, one out of each of the lead signals to be connected to inputs of the single amplifier channel, wherein the single amplifier channel amplifies all of the lead signals. The single amplifier channel has a software programmable AC response.一種用於放大多重信號之裝置,其包括:多個感測器,其中多個引線信號自該等多個感測器被導出;多個供過濾與緩衝該等多個引線信號之低通濾波器和緩衝放大器;一個或多個多工器,其中來自該等多個低通濾波器和緩衝放大器之輸出被輸入至該一個或多個多工器之一;一單一放大器通道,其中該一個或多個多工器之輸出被輸入至該單一放大器通道;以及一微控制器,其控制該一個或多個多工器,其中該微控制器儲存有軟體,該軟體能夠每次一個依序地自將被連接到該單一放大器通道之輸入的各該引線信號中選出一個,其中該單一放大器通道放大全部該等引線信號。該單一放大器通道具有一可軟體程控的交流響應。120a~120i...緩衝放大器130...RL-驅動電路140a、140b...類比多工器150...差動放大器160...可程控(PGA)增益放大器170...抗膺頻濾波器180...類比至數位轉換器(A/D)190b...軟體快速基線恢復演算法190a...以軟體實作之低通數位濾波器200...數位至類比轉換器(D/A)210...數位輸入/輸出220...微控制器230...電腦240...緩衝衰減器
