Application of Limiter Amplifiers to Stereophonic Signals

Abstract

In stereophonic broadcasting, as in monophonic broadcasting, it is desirable to use compression of the peaks to prevent spurious responses and distortion in the detected signal. In stereo, however, a choice must be made between compression of the left (L) and the right (R) audio signals, or compression of L+R and L-R signals which may be derived from the original L and R signals. The latter choice has the advantage of permitting a higher mean level of modulation, but to a degree which depends upon program content. Using typical stereophonic program material, a study has been undertaken to determine mean signal levels and subjective differences in sound quality for the two methods.
