    摘要: A radio communication device using a quadrature modulation-demodulation circuit which enables DC offset error fluctuation to be corrected more accurately regardless of the condition of temperature variation or power source voltage fluctuation. A quadrature demodulation circuit inputs therein a QPSK signal to output a base band signal perpendicularly intersecting to the QPSK signal. A base band signal generation circuit inputs therein a transmission data to convert into two analog base band signals perpendicularly intersecting with each other. A quadrature modulation circuit inputs therein the analog base band signal and modulated frequency signal to output the QPSK signal. A switching circuit selects either one of the analog base band signal and the QPSK signal. An A/D conversion circuit quantizes an output signal of the switching circuit. An offset error detecting means detects DC offset error. Consequently, the radio communication device causes the DC offset error caused by temperature variation and power source voltage fluctuation to be reduced regardless of on operation.

    摘要: A frequency stabilizer for use in a time-division multiplexed digital cellular system is designed to reduce the consumption of electric power by means of a receiving circuit in continuous frequency control. The frequency stabilizer includes a pair of latches 4 and 5 for latching a phase error of an output signal from a phase error integrating circuit 2, a subtractor 6 for outputting the difference between respective output signals from the latches 4, 5, and a selector switch 8 for selecting and outputting an output signal from a phase-to-frequency converter 3 in the period of a reception slot and an output signal from a frequency correcting circuit 7 between reception slots. When the selector switch 8 is selecting the output signal from the frequency correcting circuit 7, no electrical energy is supplied to the receiving circuit. Even when the frequency stabilizer is in continuous operation, the receiving circuit operates only during the reception slot, resulting in reduced consumption of electrical energy.

    摘要: A method for feedback controlling air-fuel ratio of the mixture supplied to an internal combustion engine having a plurality of cylinders comprises the steps of, detecting respective air-fuel ratios of the exhaust gas from the respective cylinders with an air-fuel ratio sensor having a substantially linear output characteristic; calculating an average air-fuel ratio by using the latest detected air-fuel ratios of the respective cylinders; determining a fundamental feedback correction coefficient .beta..sub.0 for a cylinder of which air fuel ratio is feedback controlled next; retrieving a learning correction coefficient .beta..sub.1 for the cylinder of which air-fuel ratio is feedback controlled next from a learning map prepared by learning for the corresponding cylinder; and determining new learning correction coefficients .beta..sub.1 for the respective cylinders using respective deviations of the respective detected current air-fuel ratios from the latest average air-fuel ratio calculated in the previous step, whereby air-fuel ratio control at any desired air-fuel ratio is carried out with a high accuracy and with a uniform air-fuel ratio throughout the whole cylinders.
