ABSTRACT:
A carrier signal bearing digital data which varies a characteristic of the carrier signal during each baud period in a predetermined manner to identify the baud value during the period is demodulated by subdividing each baud period into n intervals, converting the carrier signal characteristic to a DC signal which is integrated over each of the intervals and summing the integrated DC signal attained at the end of each interval with the integrated DC signals attained at the end of the previous n-1 intervals.
