A – Audio Processor


On this module the HF audio signal (time base corrected) will be split up and demodulated into the 2 possible audio signals. Drop out correction takes place for both channels. On/off switching of one or both of the audio signals is possible on this module. The HFaudio signal, time base corrected, (HFATBC) comes from the ETBC B module (H). This signal is fed through 2 identical circuits for both audio channels. Only some values of the applied components differ because of the different subcarrier frequencies (audio-1 :683kHz, audio- 2:1066kHz).
