<P>PROBLEM TO BE SOLVED: To display frequency domain data multilaterally at different frequency resolution and time resolution. <P>SOLUTION: First type frequency domain data generated by the first type frame unit from time domain data of a signal to be measured are displayed as a spectrogram. A selection frame for selecting a plurality of first type frames is displayed on the spectrogram. This signal analyzer generates second type frequency domain data by treating time domain data of the selected plurality of first type frame portions as new one frame, and displays the data as a spectrum. Resultantly, the spectrum and the spectrogram become different frequency resolution and time resolution. <P>COPYRIGHT: (C)2010,JPO&INPIT |
