Title :
Factors Affecting the Threshold of Feedback FM Detectors
Abstract :
A signal dependent threshold condition is often observed in feedback FM detectors. It is shown in this paper that this is due to the shape of the discriminator characteristic, and that in general a great deal of care is needed in discriminator design in order to reduce this effect.
