    • An antenna-integrated strip line cable with which it is possible to improve the performance of a high-frequency appliance such as a portable telephone without making the appliance larger. An antenna-integrated strip line cable 1 is made up of a transmission line part 2, an antenna part 3 and a counterpoise 4. The transmission line part 2 is made up of two conductors 21, 22 disposed in parallel, insulators 23, 24 having plasticity or flexibility disposed between these two conductors 21, 22, and a central conductor 25 disposed between the insulators 23, 24 centrally in the width direction thereof. Wide-pattern impedance matching circuits 26a, 26b are provided in the central conductor 25. The antenna part 3 has portions of the insulator 24 and the central conductor 25 extending from the transmission line part 2. The counterpoise 4 has portions of the insulator 23 and the conductor 21 extending from the transmission line part 2. The counterpoise 4 is perpendicular to the antenna part 3 and the length of the counterpoise 4 is about one-fourth of the wavelength .lambda. of the frequency used. Some benefits of this novel construction are that the number of parts is reduced, the work of connecting a coaxial cable to an antenna is made unnecessary, the counterpoise reduces directivity of the antenna part, the antenna is tough, and it is not necessary to provide an impedance matching circuit externally.

    • A digital filter circuit has two decimation filters, a first and a second, for performing two decimations with respect to a digital data of a predetermined sampling rate. The first decimation filter has a function of producing processing signals for a filter coefficient of the second decimation filter and providing such operational signal to the second decimation filter. Since the output of the first decimation filter is not a coded numeral value but is an output in the form of a processing signal for the filter coefficient of the second decimation filter, the first decimation filter can take the form of a decoder circuit and not an operational circuit and the second decimation filter can be simpler than that having a multiplier circuit of a conventional circuit. The scale of the overall circuit can be reduced and this contributes in the enhancement of high integration of large scale integrated circuits (LSIs), in the scaling down of chip areas and in reducing the manufacturing cost.
