Published:2009/7/3 4:13:00 Author:May | From:SeekIC

Used in offset frequency-measuring system for amateur-band signals. Nine-section Chebvshev high-pass filter with 1-dB passband ripple attenuates undesired 2.045-2.245 MHz image 16 dB while selecting desired 2.955-3.155 MHz signal. Filterhas sharper cutoff characteristic, for given num ber of sections, than Butterworth or image parameter designs.-J. Walker, Accurate Frequency Measurement of Received Signals, Ham Radio, Oct. 1973, p 38-55.
