    摘要: An FSK data receiving system is provided which is capable of constituting a direct-conversion receiver suitable for realizing an integrated circuit, is capable of decoding in a wide receiving band width, and is capable of realizing a small-sized and less-electric power consumption data receiving. An FSK-modulated local oscillator signal 3 is applied to a local oscillator 2, and there is provided a decode circuit 15 which obtains the decode signal 14 by judging whether the FSK-modulated frequency deviation of the carrier wave signal 1 is a positive deviation or a negative deviation on the basis of a comparison result of a voltage change in a frequency-voltage conversion circuit 16 for a base-band signal 8; i.e. the output signal of a frequency mixer 6. An offset amount of the local oscillator frequency is judged by a voltage judging circuit 17 to produce a control signal 18 Further, there is provided another decode circuit 22 which makes a judgement of frequency change of the base-band signal 8 and a judgement of in-phase/opposite-phase relationship from the decode signal 14 and the output of the voltage judging circuit 17 so as to obtain a decode signal 23. Moreover, there is provided a decode signal processing circuit 25 which obtains a decode signal 24 from the decode signals 14, 23 in response to the control signal 18.

    摘要: A direct-conversion receiver includes a direct-conversion demodulator. A first device detects a strength of a received signal. A clock signal generator outputs a clock signal in response to a reception start signal. The clock signal has a frequency corresponding to a symbol rate or higher. A second device samples an output signal of the demodulator at a timing determined by the clock signal. A third device samples an output signal of the first device at a timing determined by the clock signal. A fourth device stores "n" output signals of the second device which relate to a signal periodically transmitted from a transmitting station "n" times, wherein "n" denotes a natural number equal to 2 or greater. A fifth device stores "n" output signals of the third device which correspond in timing to the "n" output signals of the second device. A sixth device reads out signals from the fourth device, and reads out signals from the fifth device. The sixth device weights the signals read out from the fourth device in response to the signals read out from the fifth device. A seventh device combines output signals of the sixth device.
