Document Type and Number:
Japanese Patent JP2014204824
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To transmit a biological signal of a plurality of channels in real time through wireless communication.SOLUTION: A mobile type biological signal transmission device has: a plurality of analog sensor sections in which a biological signal is input; a plurality of AD converters which convert the biological signal into a digital biological signal; a bandpass filter which eliminates a predetermined band composition of the digital biological signal; a moving average filter which performs moving average of the digital biological signal to be outputted from the bandpass filter; a frequency conversion section which converts the frequency of the digital biological signal to be outputted from the moving average filter; and a communication section which transmits the digital biological signal to be outputted from the frequency conversion section wirelessly.
