ABSTRACT:
In a signal recording circuit, a dither signal in a frequency band of from a frequency higher than 1/2 of the sampling frequency of a recording signal to a frequency lower than (n-1/2) of the sampling frequency (where n is an integer larger than 1) is added to the recording signal in an addition circuit, and the output of the addition circuit is subjected to analog-to-digital conversion with a frequency n times the sampling frequency.
