Abstract
A signal processing device () includes a noise generator () configured to have a noise strength set therein and to output a noise with a set noise strength; a noise adder () configured to add the noise to an input signal including a weak signal as a measurement target to generate a noise-added signal; a threshold processing circuit () configured to perform threshold processing on the noise-added signal; an evaluating circuit () configured to extract, from an output signal output from the threshold processing circuit, a pulse signal component that meets a pulse waveform condition and to evaluate the extracted pulse signal; and a strength setting circuit () configured to set, in the noise generator, a noise strength to a desired value based on an output from the evaluating circuit.
