Abstract
A noise reducing circuit for a frequency discriminator is disclosed for providing a frequency discriminator with reduced sensitivity to noise. Reducing the sensitivity to noise allows certain distortion measurements, such as the well-known SINAD test for broadcast receivers, to be made in the presence of high noise levels.
