Abstract
A pulse detector that detects a pulse signal originating from the pulse of a human body includes: a pulse wave sensor that detects and outputs a first pulse wave signal in which the pulse signal and a noise signal are mixed; and a first filtering unit that generates an adaptive spectral line enhancer based on the first pulse wave signal, divides the first pulse wave signal into a first signal and a second signal, and outputs a second pulse wave signal including at least the first signal.
