Abstract

PURPOSE:To process input signal with various frequencies by generating a timing signal of a frequency in proportion to a recurring frequency of a digital signal. CONSTITUTION:The timing signal (clock signal) for the arithmetic processing of a digital low pass filter 43 is set so as to have proportion to a recurring frequency (fundamental frequency) of the digital signal outputted from a digital signal generator 10. Thus, it is possible to keep the gain characteristic and phase characteristic of the digital low pass filter 43 constant regardless of the frequency change in the input digital signal of the digital low pass filter 43. Since the digital signal is formed by using an up-down counter, the recurring frequency (fundamental frequency) of the digital signal is recognized in advance. Thus, the timing signal of the digital low pass filter 43 is formed easily.
