Abstract
A signal processing device () includes noise reduction units (), cascade-connected to each other, each of which includes: a signal selection section () for selecting a representative value from sampled signals obtained from an input signal by sampling a target signal and signals which are away from the target signal by given intervals; a voltage determination section () for determining which of a determined representative value and a voltage of the target signal is larger; and a signal output section () for increasing or decreasing the voltage of the target signal depending on a result of the determining and outputs the target signal as the output signal. A combination of intervals between the target signal and the signals excluding the target signal vary from noise reduction unit () to noise reduction unit (). A noise reduction unit on a more upstream side has a larger maximum value of the intervals.
