ABSTRACT:
In a bandlimited recording or transmission system utilizing broadband limiting and high-frequency pre-emphasis followed by clipping, a unique combination of a lowpass filter and shelving filter are used to limit channel overload exhibited by prior art clipping and anti-aliasing filters. The pre-emphasis employs a split path signal flow, with a voltage controlled amplifier used on the high-frequency signal path.
