    • A digital tuning system (250) for changing a cutoff frequency of an analog filter (132) includes digital synthesizers (292 and 294) for producing a two-tone calibration signal (196) applied to an input of the filter after a quality factor of the filter is increased. The filter includes at least one R/C circuit with two resistors (304 and 306) for changing the quality factor and arrays (308 and 310) of capacitors for changing the cutoff frequency. The amplitude of the magnitude responses (409 and 411) of the filter to each tone (405 and 407) is measured by a two discrete Fourier transform single-frequency bin power detection circuits (253 and 254) while the filter is sequenced through a plurality of capacitance settings. An optimal capacitance for the R/C circuit is selected by comparing, to a pre-selected value, a difference between the responses of the filter to each tone, for each capacitance setting.

    • PURPOSE: A method and an apparatus for controlling a passing band of HPF(High Pass Filter) are provided to optimize a receiving rate of data by changing a resistant value according to the intensity of signals. CONSTITUTION: A method for controlling a passing band of HPF includes a signal receiving process, a signal comparison process, a control signal outputting process, and a resistant value control process. The signal receiving process is to receive the first signal. The comparison process is to compare the first signal level with the predetermined signal level. The control signal outputting process is to output a control signal according to a result of the comparison process. The resistant value control process is to control a resistant value in response to the control signal. A passing band of the HPF(50) or an interrupting frequency is decided by the resistant value.
