CARRIER GENERATION FACILITY FOR A DIGITAL MPX-SIGNAL DEMODULATOR

摘要

A digital MPX signal (mpx1) contains a pilot signal (p1) that has a coupled clock signal (t1) . Carrier signals are generated (x1.1,x1.2) by a pilot signal phase locked loop (10).A control circuit (60) delivers a start value (i0) and phase correction values (k1,k2). The start signal fixes the search range for the pilot signal and the correction values are used by a pair of stages.
