Abstract: 1,173,351. Analogue-digital converters. WESTERN ELECTRIC CO. Inc. 8 Feb., 1967 [23 Feb., 1966], No. 6028/67. Heading G4H. A pulse code modulation encoder comprises a modulator 14 (Fig. 1) for modulating a high frequency carrier with a voltage which is representative of the unknown signal E s , a series of phase-responsive stages 17, 18, 19 for generating a first output voltage in response to the phase of high frequency carrier energy applied thereto, each stage also including means for generating a second output carrier voltage for transmission to the next stage, means being included between each stage for applying reference high frequency energy to shift the phase and magnitude of second output carrier voltage of successive stages. In one embodiment a balance modulator 14 to which is fed a signal E a  and a high frequency carrier signal E c  delivers an output signal E 1IN  having an amplitude proportional to the input signal E a  but being of one of two phases O or # depending on the polarity of E a . This signal is fed to the first stage 17 the output from which comprises a positive or negative signal Ed 1  depending on the polarity of E a  and a signal E 1OUT  having the same amplitude as E 1IN  but having a zero phase. This is fed to the next stage 18 where it is mixed with a high frequency reference signal of amplitude proportional to the maximum possible value of E a . This stage similarly gives two output signals, a signal Ed 2  depending on the phase of the mixed signal and an output signal E 2OUT  having the same amplitude as the mixed input signal but of zero phase. The latter signal is similarly applied to the next stage 19 where it is mixed with a reference signal having half the amplitude of the previous reference signal. The outputs E d1 , E d2  . . . are fed to a combiner 22 having appropriate delay means so that a train of pulses E p  is obtained representing the analogue input in Gray's binary code. By modifying the stages (Fig. 9, not shown) the output may be normal binary code.
