General Description

Multistandard satellite sound IF device consisting of a mixer and a voltage controlled oscillator (VCO) as a fre-

quency converter that can be continuously tuned in 10 kHz increments with crystal accuracy by means of a

The AF signal passes through two switches. Each switch can select the AF sources and the mono / stereo

mode the de-emphasis networks together with the two following volume control stages with audio buffers.

In front of one FM section an IF multiplexer is used to select the IF bandwidth.
