Title: Latching and control circuit for carrier detection
IPC: H04L27/14
Filed: 1972-09-11
Abstract: A carrier detection circuit for a modem receiver wherein a carrier detect flip-flop is latched upon receipt of initial mark signals of a message. Logic circuits responsive to end-of-transmission signals, noise and signal drop-out control turn-off of the flip-flop. Probability of turn-off due to noise is reduced by delaying turn-off signals due to noise, whereby only a message end code causes rapid turn-off. In addition, a circuit is provided requiring the received signal be in a marking state to enable a fast turn-off.

Title: Single channel duplex communication system.
IPC: H04L27/12
Filed: 1981-08-26
Abstract: A single channel duplex transmitter/receiver utilizing digital frequency shift keying (FSK) signals. An analogue-to-digital converter frequency modulates the output of a local oscillator whose output is coupled via a mixer/combiner/splitter network to an aerial. FSK signals received from the aerial in the receiver are mixed with the local oscillator output in network to provide quadrature signals which are low-pass filtered before being demodulated in a zero IF demodulator to give a digital output. To avoid unwanted sidetone the output of the A/D converter is fed through a delay to a digital network where it is subtracted from the corresponding signals fed back through the demodulator. The digital signals are then fed to a D/A converter.

Patent ES-8303868-A1 (ES)
Title: Arrangement for automatically controlling the bias voltage of a picture tube
IPC: H04N9/20
Filed: 1982-01-19
Abstract: The subject-matter of the invention is an arrangement, used in a system processing video signals, for automatically monitoring and controlling the blanking current (black-level current) of a picture reproduction tube. During periodic monitoring intervals in which no picture signals appear, an output signal is generated at the cathode of the picture tube which is proportional to the black level of the cathode current. This cathode signal is produced as a reaction to a grid control pulse applied during the monitoring interval. The cathode signal produced is processed in a digital signal processing circuit (70, 76, 77) in order to generate a control voltage which changes step by step and which, if necessary, changes the cathode bias voltage in such a direction that a desired value for the black level cathode current is obtained. To prevent the system from starting to oscillate in the vicinity of the correct cathode bias voltage, the grid control pulses (GP2) are given a special shape in particular development of the invention.
