SIGNAL TO NOISE RATIOS FOR MULTIPATH COMBINERS. PART III. ON THE STATISTICS OF A CLIPPER OUTPUT.
Abstract
The conclusions of the report are: The loss in output signal to noise ratio caused by using a bandpass clipper preceding the filter matched for the signal is several db for signals 0 to 10 db weaker than the noise, less than 2 db for signals more than 10 db below the noise, tending to zero loss for very weak signals. This assumes that the non-clipping operates ideally (ignoring any saturation difficulties that might occur.) If the system uses the envelope, the loss will be virtually the same; and if it uses the envelope squared the loss will be 3 db bigger. (Author)
