Title: Signal detector
Inventor: AKATA MASAO
IPC: G01R23/167
Filed: 1987-02-05
Abstract: PURPOSE:To enable the execution of detection of high precision with a small quantity of hardware and software by a method wherein the amplitudes of an output signal of a band-pass digital filter and a signal obtained by passing said signal through a phase shift filter are compared with a threshold value. CONSTITUTION:A band-pass digital filter 1 receives a digital input signal 4 sampled at a prescribed sampling period and outputs a digital output signal 5 which is a sample train having a frequency component of a signal to be detected. A phase shift filter 2, whose gain is 1 substantially in relation to the frequency component of the signal to be detected, receives the signal 5 as an input, applies a phase shift to the frequency component of the signal to be detected, with n/1 [(n) is an integer of 2 or more] of the sampling period taken as a unit delay time and with each shift made by (m) times [(m) is 1,2,...n-1] of the unit delay time, and delivers a digital output signal 6. Then, an amplitude comparator 3 compares the amplitudes of the signals 5 and 6 with a threshold value set beforehand, and when the amplitudes exceed the threshold value, it determines that the signal, the object of detection, is detected.
