The digital signal processing part always appears, and removesas a noise a frequency band of which spectrum hardly change within a predeterminedtime period. Moreover, the digital signal processing part sets a frequency band with acomparatively large spectrum change as an FSK modulation signal corresponding to codecontents, and outputs binary data corresponding to the frequency band as a code signal.
