Abstract
PURPOSE: To avoid the undesired oscillation, by forming such constitution in which the unnecessary oscillation loop may not be formed.
CONSTITUTION: In case the analog signal is recorded after converted into the PCM digital signal, the switch S1 is first turned on to supply the analog signal to the input terminal IN. Then the signal which is digitized through the A/D converter 12 and via the amplifier 11 is supplied to the digital mixer 22 via the switch S1. This digital signal from the mixer 22 is supplied to the video tape recorder 16 via the PCM recording system 15 to be recorded there. If only the switch S1 is turned on, the on- command is given to the switch S3 from the detection circuit 28, and thus the recording is possible through the video tape recorder 16a which is originally provided for recording, dubbing and other purposes. When the switch S2 is turned on, the circuit 28 gives the off-command to the switch S3 to avoid a formation of the oscillation loop.
