IPC: H03L7/099
Filed: 2003-02-05
Abstract: <P>PROBLEM TO BE SOLVED: To obtain high attenuation characteristics over a wide range of frequencies.  <P>SOLUTION: In this band characteristics control method, a control voltage of a VCO is used, the voltage is input in a receiving band-pass filter, and the characteristics of a pass-band of the filter are controlled by the control voltage, according to the circuit frequency. Attenuation of the filter can be increased by voltage control input of the filter. Deviation of the characteristics of the pass-band of the filter can be corrected by changing the control voltage, and by the correction, attenuation can be kept constant. Not by continuous change but by stepwise change of the control voltage, can the purpose be sufficiently realized. The stepwise change can be obtained easily by selecting the resistance. It is preferable to reduce the range of the control voltage by switching the characteristics of the VCO. It is more preferable to detect the temperature and correct the temperature characteristics of the filter.  <P>COPYRIGHT: (C)2003,JPO
