Abstract
A frequency discriminator comprising a power splitter for splitting a signal into first and second paths, wherein the first path is configured to provide a first, straight-through signal and the second path includes a frequency-dependent element, such as low-pass filter, so as to provide a second signal. The frequency discriminator further comprises a circuit configured to compare the first and second signals and generate an instantaneous frequency signal in dependence thereon.
