IDEAL LIMITING. PART I. THE EFFECT OF IDEAL LIMITING ON SIGNALS AND ON NOISE,
Abstract
The effect of hard clipping or ideal limiting on sine-wave signals and on shaped, Gaussian-noise inputs is considered. For a single sine wave, the limiter reproduces the fundamental frequency and creates odd harmonics of rapidly decreasing relative power. For two sine-wave inputs of equal amplitudes, the limiter generates arrays of heat frequencies centered symmetrically about the two input frequencies and their shifted odd harmonics. If the two inputs are of unequal amplitude, the stronger signal suppresses the weaker. On shaped, wide-band Gaussian noise, the limiter tends to broaden the high-frequency end of the spectrum slightly and to produce a flat, low-frequency, random-noise response. (Author)
