Claims

[Scope of utility model registration request]

a pitch extractor that outputs according to the fundamental period of the input signal;
The frequency of the pulse train output from the pitch extractor is λ
an M multiplier that multiplies by 4, a counter that converts the M-multiplied pulse train into an address signal, and a control device that outputs a control signal based on the output pulse of the pitch extractor and the output pulse train of the M multiplier; an analog-to-digital converter that converts the input signal into a digital signal according to the control signal; a storage device that is called or stores the digital signal according to the address signal; and a storage device that converts the digital signal output from the storage device into an analog signal. A signal generator consisting of a digital-to-analog converter.
