Abstract
PURPOSE: To prevent lowering of S/N even if the number of conversion bits is reduced and suppress reproduced output wave distortion, by performing digital conversion after FM modulation of the audio signal.
CONSTITUTION: The input audio signal supplied to terminal 1 is supplied to FM modulator 3 after having band-limited properly. FM-modulated signal is converted to a digital signal by A-D converter 4. This digital signal is supplied to digital memory 5 and has the time base compressed and is supplied to D-A converter 6 and is converted to an FM signal and is supplied to magnetic head HV through low-pass filter 7 and recording amplifier 8.
