You can't change the average level without changing the waveform. Bovine excrement. An amplifier will increase the average level, but by increasing all levels. As many references make clear (some listed below), an amplifier does NOT change the waveform. The perfect amplifier or audio processor, would create zero distortion - no change to the waveform. However, the perfect circuit does not exist so some distortion will occur in any active circuit. This includes circuits already in the radio. A processor may be any circuit that carries out the process the designer (or marketing person) has decided on. This could be as simple as an amplifier... it is carrying out a process. A processor which simply amplifies all signals and clips the higher levels can produce much distortion. A well designed and adjusted processor could produce little more distortion than a simple amplifier. The question is whether "Telstar" and "well designed" go together. I would like to see an independent review from someone without an axe to grind. Regards, Peter. http://www.citizensband.radiouk.com/ Ref 1 - Electronics for engineers. R. J. Maddock & D. M.
