    摘要: A tuning circuit for tuning a high frequency receiving apparatus with residual sideband modulation, especially a television receiver, with a counter for forming encoded values of tuning voltage, with a store for the digital storing of the encoded values of tuning voltage, with a D/A converter for generating the analog tuning voltages from the encoded values and with a circuit for automatic fine tuning to the required position of a received transmitter. In such tuning circuit means are provided which so alter the value of the tuning voltage before or during writing into the store or after or during reading out from the store that this value corresponds not to the required tuning position but to a tuning position shifted into the fully transmitted sideband. The exact tuning ot the transmitter to the required position is effected by the circuit for fine tuning.

    摘要: A frequency sensitive network responsive to frequencies somewhat above the useful signal band of a demodulated radio signal is interconnected with the inputs of a differential amplifier, so that the desired signal and the portions of the interference signals unaffected by the frequency sensitive circuit cancel out and a "stripped" interference signal is obtained which is fed to a transistor circuit that produces trigger pulses for a multivibrator, regardless of which side of the differential amplifier first produces a pulse. The multivibrator provides pulses to a blanking switch and also charges a capacitor in a RC network, in which charge accumulates when the control pulses are bunched closely in time and this effect is used to produce a bias for disabling the provision of trigger pulses to the multivibrator until the capacitor charge leaks off.

    摘要: The invention relates to an electronically controlled ignition system in which a correction signal is obtained from a control signal derived directly from an ignition pulse sensor. The invention consists of producing a saw-tooth signal with a rising flank and a falling flank within one cycle of the square wave control signal, using only one flank of the said control signal. The ratio or relationship between the gradients of the two flanks is a measure of the change in the corrected signal relative to the control signal. The electronically controlled ignition system is particularly suitable for compensating for the ignition advance, caused by an induction sensor, as compared to the mechanical position of the rotor at low engine speeds.

    摘要: The circuitry is used, for identifying television transmitters, in a television set receiving synchronizing signals and line flyback pulses characteristic of television transmitters, particularly for television receivers including a station finder circuit. The circuitry, during the time period of the line flyback pulses, derives samples of those signals appearing above the black level of the video signal, from the demodulated input signal. The number of amplitude jumps determined during the time period of the line flyback pulses is utilized as the criterion for identification of a television transmitter. The signals appearing above the black level of the video signal are inverted and then combined, in an AND circuit, with the line flyback pulses, and the output of the AND circuit is connected to a digital counter circuit to supply the output pulses thereto as counting pulses, with the flyback pulses being supplied to the digital counter circuit as gate pulses. An inverter is connected to the output of the counter circuit and a logic "1" potential appears at the output of the inverter only in the case where a single pulse has been delivered to the counter circuit during the gate time, with a logic "0" potential appearing at the output of the inverter in all other cases. The output of the inverter is connected, through an integrating circuit, to a threshold circuit providing an output signal which indicates whether a television transmitter has been identified.

    摘要: An ignition system has an electronic control unit which produces trigger pulses in response to received ignition control signals, the control unit also receiving test pulses indicating the period of time for which current supplied to the primary winding of the ignition coil is at its maximum value, the control unit extending the test pulses and supplying the extended pulses to a logic circuit which, when a trigger pulse occurs without an extended pulse simultaneously occurring, produces an output signal to indicate misfiring, and to temporarily switch off the control.
