  • System for demodulating a digital modulated wave
    Patent number: 3992673
    Abstract: A system for demodulating digital phase-modulated wave having signal elements of constant length by detecting in a detector the signal wave elements during every period of substantially the constant length, in which a combining circuit is further provided for estimating digital information content of the signal wave elements by the use of a combined output of detected results obtained by sequentially detecting, the information content of successive two of each signal wave element of the detected output of the detector, so that a demodulated output is obtained by selecting one of the outputs of the detector or the combining circuit.
