![]() We have tubes, hybrid and SS stereo decoders. We have integrated devised and discrete stereo decoders. ![]() Well, we have a number of different topologies the phase locked loop stereo decoders, the pulse-count stereo decoders etc. As soon I activate the stereo decoding I get noise – so would it be the stereo extraction itself that screw the things up? All front ends have own noise capacity but how about the stereo decoders? If I run a tuner in mono and have no FM noise then I presume that my frond end and IF sections are fine. If with the first 4 parameters everything is understandable then with the last parameters the things are perplexed. In my experience the same stations of excellent reception might have fluctuation on FM stereo noise depending of: I would not consider the minor FM noise is destructive – in fact I kind of like it – it has a slight dithering effect but I still wonder…. So, why we even have to have the FM Stereo Noise? Is it the fundamental entity of FM reception of juts bad implementation of some specifics? The best tuners more then 85dB signals to noise ratio – that are very high number and the typical hiss the we get in stereo is not even closed to the electrical signal-to-noise characteristics of out tuner. I was wondering what the noise of stereo signal come into FM and are any ways to reduce it? Naturally we get out stations in mono mode with practically no noise at all.
