  • Devices, systems and methods for composite signal decoding employing interpolation filter
    Patent number: 5471534
    Abstract: A device and method for composite signal decoding is provided in which an analog-to-digital converter (15) digitizes an incoming FM composite signal. The digitized signal is filtered by an interpolator (13) which uses filter coefficients developed as a function of a sampled pilot signal's phase without synchronizing the decoder sample rate to the pilot signal to reconstruct the composite signal at points Where the pilot signal phase is a multiple of 45.degree..
