VSB encoder and RF Modulator for low-cost Supply a substantial Signal 6 MHz to a VSB digital television Receiver

摘要

A system provides a compressed Digital Signal to a digital television receiver includes a baseband Signal Source compressed.An encoder encodes the base Band signal in a Digital Format, and the base Band signal has a Frequency.The frequency of the base Band signal is encoded by a First Frequency Deviant diverter.A First interpolator interpolates a First diverter, output frequencyA Second interpolator interpolates a departure from that first interpolator and a Third that interpolator interpolates a output of the second Interpolator.A deflector deflects a Second Frequency, frequency of an output of the Third interpolator to produce a signal on a Channel selected.
