Abstract

PURPOSE:To attenuate a power level of a frequency band desired to be removed, by sweeping the band with a waveform signal having steep rise and fall instantaneously. CONSTITUTION:A trigger pulse generator 8 consists of a mixer 8a, a reference oscillator 8b and a low-pass filter 8c, and a signal in 125-155MHz intermediate frequencies outputted from a frequency mixer 5 is applied to one input of the mixer 8a, and a reference frequency corresponding to a frequency f0 (e.g., 138MHz) among this intermediate frequency band signal is applied to another input for mixing. This mixed output is applied to the low-pass filter 8c having 500kHz cutoff frequency to generate a trigger pulse at a time location before the generated time location of the frequency f0 by 0.5mus. After this trigger pulse is converted into a rectangular wave signal, 1mus in width having steep rise and fall at a wave signal generator, the pulse is applied to a local oscillator 4 to instantaneously change the oscillated frequency.
