The H.F. signal of the disc will be spit up into a video and an audio signal in this module. The H.F. signal goes to the H.F. video processor section. After a highpass filter an adaptation of the frequency response will take place there by means of the MTF voltage. This is necessary dependent on the readout diameter of the disc. The corrected H.F. video signal will be demodulated in IC 7201. After filtering and amplification output signal CV-DEM will be available for further processing at module L (drop-out correction). The H.F. signal also goes to the H.F. audio processor where the audio is filtered out by means of a lowpass filter. Output signal HF-AUD will be timebase corrected at module H.
