Filed: 1978-04-07
Abstract: PURPOSE:To easily obtain the filter excellent in the cut off characteristics with small size and light weight, by converting once the signal filtered to modulation waves, and by demodulating the modulation waves obtained through the filter having required filtering characteristics. CONSTITUTION:The signal from the signal source 1 performs amplitude modulation for the carrier of frequency fo from the carrier oscillator 6 at the amplitude modulator 2. This modulated wave is passed through the band pass filter 3, and the frequency spectrum of the modulated wave is fo+fc to fo+fB and fo-fc to fo-fB for the frequency region, where the maximum and minimum frequency are fc and fB, and the filter 3 picks up the frequency component within the range of fo+fA to fo+fB. This is demodulated at the demodulator 4 in frequency fo to pick up the signal within the range of fA to fB. This signal is passed through LPF5 and the  carrier is rejected. Thus, since the filter 3 can be constituted by using the element  having remarkably high Q and of which operation frequency is limited, crystal  resonator and ceramic resonator can be used.
