ABSTRACT:
Pulse code modulated signal apparatus has a recording mode and a reproducing mode and comprises input terminals for respectively receiving input signals, a digital-to-analog converter for receiving a reproduced digital input signal in the reproducing mode and producing an analog output signal corresponding thereto, and switch circuitry for making a selection of the input signals, the analog output signal and a non-signal and producing a switched output corresponding thereto. A filter filters the switched output. A control circuit controls the switch circuit in the recording mode to select one of the input signals and in the reproducing mode to select alternately the analog output signal and the non-signal, thereby providing aperture compensation.
