  • Procedure and circuit for detection of the information of a received signal
    Patent number: 4745627
    Abstract: Two phase-shifted quadrature signals are formed from a reception signal modulated by frequency-shift keying. Instant values of one of the quadrature signals are taken at the instant when the other quadrature signal passes through zero and vice-versa. The readout values obtained during an interval of one data bit are alternatingly inverted in their polarity or left unchanged, so that a sequence of readout values of adapted polarity is formed. The values are algebraically added in an added during each of the bit intervals. The sign of the resultant sum determines the evaluated value of the received information symbol `0` or `1` and the amount of the sum is a measure of the quality of the evaluation.
