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
