Modulator

Signal programs

Signal compilation

    signal -tra -c MODUL.SIG -par=MODUL.PAR

The results are generated in the sub-directory MODUL:

Execution

The binary uses the following data files: RBIT.dat, RFE.dat and generates the file WENTREELIGNE.dat. The expected results are in the file WENTREELIGNE.OK

Demodulator

Signal programs

Signal compilation

    signal -tra -c DEMODUL.SIG -par=DEMODUL.PAR

The results are generated in the sub-directory DEMODUL:

Execution

The binary uses the following data files: RSORTIE_LIGNE.dat and generates the files: WMODERREUR.dat, WSYMBOLE.dat. The expected results are in the files WMODERREUR.OK and WSYMBOLE.OK.
