Abstract
A high-frequency device that detects biological information related to heartbeat, respiration, and the like with high accuracy. A high-frequency device () includes a biological signal extracting unit (heartbeat signal extracting unit, respiration signal extracting unit) that extracts a biological signal representing a specific frequency component; and an autocorrelation function processing unit (heartbeat autocorrelation function processing unit, respiratory autocorrelation function processing unit) that determines periodicity of an autocorrelation function to calculate biological information.
