Title: Antenna circuit
Inventor: OKUMURA ITARU
IPC: H04N5/44
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide an antenna circuit by which the operating convenience is improved without giving an effect on reception sensitivity and an external appearance with respect to a miniaturized device is not deteriorated by configuring the antenna circuit without the use of a comparatively long rod antenna. SOLUTION: Relating to the reception capability of a dielectric antenna section 13, the receptible frequency band is made extremely narrower in comparison with that of a conventional rod antenna. Thus, since it is required to allow the antenna circuit to be tuned to each broadcast channel, a varactor diode 14 is provided in series with the dielectric antenna section 13 and a voltage generating circuit 17 applies a voltage suitable for each antenna to the varactor diode 14 to allow the diode 14 to receive a radio wave through tuning.

Filed: 1980-02-22
Abstract: PURPOSE: To remove unnecessary signals mixed in a reproduced signal and obtain the reproduced signal of a good SN ratio by passing the reproduced digital signal through a digital filter of changing cut-off frequencies corresponding to reproduction speeds.  
     CONSTITUTION: A latch 23 is supplied with the multiple detection signal from a comparator 19 corresponding to the ratios between basic clock pulses and the output of a decorder 18 corresponding to reproduction speeds, and therefore, the output from the latch is read at these new timings and is supplied to a DA converter 24 and an RAM25 respectively. Since the analog signal read out after DA conversion 24 has been inputted to the DA converter 24 after the digital signals of bands from 1/2fs up to about 1/4fs have beforehand been removed thereform, the reproduced analog signal of a high SN ratio is obtained without being mixed with folding distortions. Similarly, the signal components of bands from 1/4fs up to about 1/2fs are not contained in the output signal of the latch 23; therefore, no folding distortions are mixed in the digital signal which is stored into the RAM25 and is read thereform, thus the reproduced digital signal of a good SN ratio is obtained.
