Abstract:
1. A digital processor, comprising: a voltage controlled oscillator having a control voltage input and an output outputting an oscillating signal; a band noise generator generating noise within a noise frequency band; an analog/digital converter into which a first analog signal of high cyclic characteristics is input, said first analog signal being based on the oscillating signal and including the noise generated by the band noise generator, the analog/digital converter converting the first analog signal into a first digital signal representative of the oscillating signal and the noise generated by the band noise generator; an adder for adding the noise generated in the band noise generator into the first analog signal input to said analog/digital converter; and a digital processing unit executing digital processing on the first digital signal converted by said analog/digital converter to produce a processed second digital signal at a digital processing unit output; a digital/analog converter provided on an output side of said digital processing unit and operating to produce a second analog signal based on the processed second digital signal, wherein:
