Abstract
The construction methods of spectrum analyzer are presented in which SAW chirp filters are used. There are two basic methods on construting spectrum analyzer: One of which is construction using chirp filters with different chirp rates, and the other is construction using filters with the same chirp rate. It is verified that the latter has better response with the less spurious, in spite of the simple fabrication capability. The simple electrical apodization method which enables improvement of the accuracy of analized signal, is proposed and its validity verified by experiment. The construction methods of spectrum analizer with larger facility, by using filters with small TB products are also proposed and its validity verified by the experiments.
