further enhanced by use of a sinusoidal correction filter which minimizes error caused by the linear interpolation performed on the sinusoidal waveform although the fm demodulator circuit is particularly suitable for demodulation of the chroma component of a secam video signal it may advantageously be applied in a wide variety of fm demodulation applications application_number US 99838604 A description referring now to fig1 an exemplary personal video recorder pvr 100 is shown pvr 100 is an exemplary use of analog video decoder 102 and it is understood that the analog video decoder can be used in multiple applications including digital televisions lcd tvs dvd recorders video capture situations and the like a radio frequency rf or broadcast signal is provided to a tuner 104 the tuner 104 provides both video and audio outputs the video output from the tuner 104 or a video signal from an external connection is provided to analog video decoder 102 the audio signal from the tuner 104 or an external audio signal is provided to an audio decoder 106 the output in the analog video decoder 102 is preferably an itu r bt 656 format digital signal which may be either an eight or ten bit signal this digital signal from analog video decoder 102 is provided to an mpeg motion picture experts group.
