REALTIME MULTIPLEXING DATA AQUISITION SYSTEM AND METHOD FOR MULTICHANNEL BIO-MAGNETIC SIGNAL

摘要

The present invention provides a multi-channel, etc. biomagnetic measurement equipment that enables real-time monitoring of multi-channel data data for efficient and accurate processing of the digitized and will be available to provide a multi-channel data acquisition system and method for multi increase the efficiency and convenience of the whole device. The multi-channel data acquisition system of the present invention is a system for acquiring and processing the data of the n-channel efficiently, the n by m pieces of analog input signal of the data channel, one output line at different times on the a multiplexer for converting the output to; An output line is connected to the multiplexer, the output to the analog input signal, A / D converter for converting the output in the order entered by the m signal in each of a number of k-bit digital data; And the A / D conversion unit to input a k-bit output signal to remove data corresponding to each of the m channel to be identified according to the input order and rearranges includes a DSP.
