Description

The demodulated FM-satellite video signal TDA6151-5X is fed via a buffer amplifier to a gain controlled amplifier. The gain control is done using an external applied DC-voltage. The output signal of this amplifier TDA6151-5X is used to drive three separate signal pathes. First of all the baseband is fed via a high pass filter with a cut off frequency of approx. 4 MHz to the input of a SAT-TV-sound processor, e.g. TDA 6160 X. A second output with a buffer amplifier TDA6151-5X is used to drive two external de-emphasis networks. After passing through the de-emphasis networks the baseband signals are fed into two inputs of the de-
