Claims (1)

[Scope of utility model registration request] A/D that converts input biological signals into time-series digital signals
a converter, a delay means that receives the digital signal from the A/D converter and generates a plurality of signals having various delay times depending on the clock timing, and receives the plurality of signals from the delay means and performs a predetermined filtering process. What is claimed is: 1. A signal processing device comprising: a processor that performs the following steps; and means for extracting an output of the processor and a signal extracted from the delay means in the same phase as the output.
