Patent CA-1084625-A (CA)
Inventor: LORECK HEINZ
IPC: H04L1/08
Filed: 1976-01-22
Granted: 1980-08-26
Abstract: s ABSTRACT OF THE DISCLOSURE           The system includes an encloding transmitting unit for converting parallel data words into timing pulse synchronized serial data words which are supplied to a transmission channel, and further includes a decoding receiving unit receiving the transmitted serial data words from the transmission channel. The encoding unit comprises a clock-pulse generator and a control circuit connected to a shift register receiving the parallel data words and having a feedback, through an inverter, from a serial work output to an additional input which is a serial work input for the inverted output signal. The shift register transmits a first pulse train representing the serial data work followed by a second pulse train representing the inverted serial data word.  The decoding receiving unit includes a second shift register having a serial data work input receiving the two pulse trains from the transmission channels and having a serial data word output. An inverting exclusive OR gate has one input connected to the serial work output of this register and another input receiving the transmitted pulse trains from the transmission channel. This OR gate monitors the non-equivalence of the first and second pulse trains, to detect transmission errors and trans-fer the errors, as error signals, to a flip-flop acting as an error signal storage.  A receiving register is connected to the shift register of the receiving unit and is operable to evaluate the transmitted data.  The error signal storage, upon receipt of an error signal, prevents such evaluation of the transmitted data in the receiving register.  The shift registers of the transmitting and receiving units are syn-chronized by timing pulses.  The system may be simplified by using a pulse modulation and may also be used for a pulse duration modulated signal.  In the latter case, a synchroni-zation bit is transmitted before each data word.  An out-standing feature of the system is that it may be used with a single simple transmission channel.     1a.

Abstract: ABSTRACT OF THE DISCLOSURE         An intercommunication system comprises a transmit channel and a receive channel.  The transmit channel includes a microphone operative in a transmit mode and a first variolosser circuit and the receive channel includes a loudspeaker operative in a receive mode, a manually gain-adjustable circuit and an automatic gain control amplifier.  The first and second vario-losser circuits each provide a variable amount of loss and permit the high frequency region of the voice-frequency band to pass therethrough and have a mode wherein the amount of loss is relatively large.  A first signal is derived from the transmit channel and a second control signal is derived from the receive channel in the transmit mode from a part in the system adjacent a hybrid transformer connecting the transmit and receive channels and in the receive mode from a part in the system adjacent the loudspeaker.  The first control signal is subtracted from the second control signal and the resulting difference signal is applied to a pair of comparators having different threshold values.          The first comparator has a threshold value corresponding to the second control signal derived adjacent the loudspeaker and the second comparator has a threshold value corresponding to the second control signal derived adjacent said hybrid transformer.          A flip-flop having first and second inputs is coupled to the outputs of the first and second comparator, respectively, and first and second outputs coupled to the first and second vario-lossers, respectively.  The flip-flop selects the variable amount of less in the first and second variolossers in accordance with the outputs of the comparators.
