Signal recording and reproducing apparatus.

摘要

A disclosed signal recording/reproducing apparatus enables a direct FM recording. An input signal is directly frequency-modulated by a digital frequency modulator (25) in digital signal form to be a FM signal. The FM signal is recorded on a recording medium. The recorded FM signal is reproduced, and frequency-demodulated by a digital frequency-demodulator (33) in digital signal form using an arc trigonometrical function to obtain the original signal. The apparatus may further comprises the conventional color under recording and reproducing type signal processing circuit which is used selectively by a mode changing switch.
