Abstract

PURPOSE:To obtain a piezoelectric band erasing filter, which prevents the attenuation distortion within pass band caused by spurious of piezoelectric oscillator and further in which only impedance guarantee at the place near inside the band of the band pass filter will do even in case a transformer is needed.
