The effect of abrupt-limiting on the output of a frequency discriminator has been treated thoroughly by Middleton. This paper considers the case of smooth band-pass limiting both for the simple differentiator and for the balanced discriminator. The error function is used as a model for the smooth limiter. The idealness of the limiter is related to the quantity "μ" - the limiting hardness. The analysis reveals that for a balanced discriminator, the output signal-to-noise ratio can be made largely immune to changes in "μ". However, for the unbalanced discriminator, the signal-to-noise is not only appreciably "μ" dependent, but also a function of carrier frequency.Sponsors
