    摘要： The present invention has a purpose to obtain an FSK data receiving system 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. The FSK-modulated local oscillator signal 3 is applied to the local oscillator 2, and there is provided the 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 the comparison result of the voltage change in the frequency-voltage conversion circuit 16 for the base-band signal 8; i.e. the output signal of the frequency mixer 6. The offset amount of the local oscillator frequency is judged by the voltage judging means 17 to produce the control signal 18, And further, there is provided the another decode circuit 22 which makes the judgement of frequency change of the base-band signal 8 and the judgement of in-phase/opposite-phase relationship from the decode signal 14 and the output of the voltage judging means 17 so as to obtain the decode signal 23. Moreover, there is provided the decode signal processing circuit 25 which obtains the decode signal 24 from the decode signals 14, 23 in response to the control signal 18.

    摘要： Two conducting lines are arranged in a ring form in a TEM-mode transmission line. The end of one of the lines is connected to the end of the other line with opposite polarity, thus forming a resonator for resonation in a half-wavelength mode. This structure, free of line discontinuity which lowers the Q value, can provide a resonator having a high Q value equivalent to that of the one-wavelength resonator. Moreover, it is satisfactory to provide a half of a length of the one-wavelength resonator. Accordingly, the structure of the resonator has reduced size but little Q-value deterioration.

    摘要： A direct conversion FSK demodulator is described. The received signal is fed into quadrature mixers (4,5) and converted to baseband I and Q signals (8,9). To recover the data sequence, the Q signal is selectively inverted (12) or not, depending upon the magnitude of the I signal, which is detected in the threshold sensing circuit (10).

    摘要： Array elements 111-1 to 111-n of array antenna 101 are arranged at respective different heights from a ground so as not to overlap to each other in a vertical direction. Received frequency conversion section 102 converts a radio frequency signal received at each of the array elements 111-1 to 111-n of array antenna 101 into an intermediate frequency signal or baseband signal. A/D conversion section 103 converts an analog signal output from received frequency conversion section 102 into a digital signal using a proper sampling frequency. Direction estimating section 105 estimates directions of an arrival radio signal in a horizontal plane and vertical plane using received digital signals obtained in A/D conversion section 103. It is thereby possible to suppress increases in the number of array elements and computation amount, and to improve estimation accuracy in the vertical direction and resolution at the time a plurality of signals arrive.
