Abstract
. A fading character of whistler traces has been studied (Yano et al.,1989). During the course of this study it is noticed that quick fading patterns of whistler waves obtained by a sound-spectrograph, sonagraph, show an inflation such as semi-circular shift to the right. In order to explain this phenomenon the fading of two artificial whistlers generated by using a digital computer and a D/ A converter was analyzed by the sonagraph. It is concluded as a result of the experiment that the rightward inflation of the trace is caused by the resonance echo of a high-Q bandpass filter mounted on the sonagraph.
