Abstract

Carrier generation facility for a switchable digital demodulator (D) of digital MPX signals (mpx ) with associated pilot signal (p ) which are locked to an arbitrary clock signal (t ). A pilot signal PLL ( ) generates a first carrier signal (x , x ) and a second carrier signal (x ) by means of a first value allocator ( ) and a second value allocator ( ), respectively. According to the MPX signal (mpx ) to be demodulated, a control device ( ) delivers a start value (i ) and at least one phase correction value (k , k ). The start value (i ) sets the capture range of the pilot signal PLL ( ) for the pilot signal (p ) according to the respective standard. In a first correcting device ( ) and/or a second correcting device ( ), the phase correction values (k , k ) correct the system-inherent phase deviations of the first carrier signal (x , x ) and/or the second carrier signal (x ).
