Abstract

A digital splitter that separates the cyclical mixed information signals by Using a method such as Phase Shift Keying PSK, the plus 46 adds the compensation value stored by the 45 phase compensator to the phase shift keying PSK data. The output from the comparator 43 minus 47 deletes the received phase difference information. Delay with a 44 delay cycle for one period, symbolic information from the sum of the data. The phase difference and compensation value from the plus 46, which results in the delay detection in this way with this digital splitter. The input signal may also be received and extracted even when the frequency of It is not the full quotient of the main clock frequency. And a frequency generator can also be used Yes, even when their frequency is not a full multiple of the frequency of the input signal to be extracted. Such a signal
