APPARATUS FOR COLLECTING MULTI-CHANNEL AND PROCESSING SIGNAL

摘要

PURPOSE: An apparatus for collecting multi-channel and processing signal is provided for decreasing a load of a host computer using a PCI bus method with respect to an interface with a host computer. CONSTITUTION: A signal detection block(100) supplies a static current for driving a sensor and detects a detection signal of the sensor. An AC/DC engaging block(200) selects an engaging state of a DC voltage to an output signal of the signal detection block(100), a signal amplification/filter block(300) for amplifying an output signal of the AC/DC engaging block(200) to a selected gain and filtering a certain bandwidth. An amplifier(700) adjusts an analog output signal to a variation(-10V through +10V) and outputs to an external audio system. A DSP block(500) performs a filtering, conversion and compression with respect to the detection signal which is collected in real time.
