...kers. The explanation of analog stereo encoder can be seen here . For digitally stereo encoder, we use 38 kHz squarewave from crystal oscillator or from PLL frequency generator. In digital method we will use chopper to make composite audio for transmitter. Figure 2 below is the simulation of 1 stat...

...lter will reduce that to 40-44 dB. As the phase shift could also have happened in the other stages following the Stereo Multiplexer (Transmitter's PLL section or even at the Receiver), one would tend to unnecessarily place the whole blame on the Multiplexer. Similarly, a change in gain over ...

...orm, or someone inadvertently disconnecting the coax transmission line. If you wish to implement a failsafe shutdown system that is triggered by loss of PLL lock, I still recommend a power supply cutoff relay for total safety however. CAUTION: This amplifier operates at very high power levels. You...
