Abstract:
1. A signal analyzer comprising: data acquisition means receiving an input signal having periodicity for acquiring sets of time domain data of respective frequency bands of the input signal wherein the frequency bands have common frequency bands in adjacent portions; and calculation means extracting sets of time domain data of the common frequency bands of the adjacent frequency bands in the acquired time domain data of the frequency bands, identifying the corresponding sets of the time domain data of the adjacent frequency bands using the extracted sets of the time domain data of the common frequency bands and converting the corresponding sets of the time domain data into respective sets of frequency domain data to combine them; wherein if the number of the corresponding sets of the time domain data of the adjacent frequency bands is less than a predetermined number, the data acquisition means acquires one of or both the sets of the time domain data of the adjacent frequency bands again.
