| Abstract: | This paper introduces a method for generating narrow pulse modulated exciting signal,which drives SAW device to generate the chirp signal. This circuit is simple and has high performance. Its carrier frequency component supperssion is over 70dB. It has little interference with other circuits. The chirp signal it generates is high in frequency,wide in frequency bandwidth and large in time width. |
