Abstract
A wideband signal analyzing apparatus for analyzing an input signal includes frequency-shifting means for generating a plurality of intermediate frequency signals by shifting a frequency of the input signal as much as respectively different frequency-shifting amounts, so that if a frequency band of the input signal is divided into a plurality of frequency bands, each of the frequency bands can be shifted to a predetermined intermediate band, spectrum measuring means for outputting a complex spectrum of each of the intermediate frequency signals, and spectrum reconstructing means for merging the complex spectra.
