Title: Method for displaying signal
Inventor: SHIMIZU SATOSHI
IPC: G06F3/048
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the display resolution without loosing a characteristic frequency component by displaying data after processing of reducing the number of data without deteriorating the information of the frequency component when the data on the frequency axis of the frequency analysis result is reduced and displayed. SOLUTION: A frequency range to be displayed is divided into a plurality of small sections A, B, C, and the average value of signal intensity is calculated for every section. Twelve original data on frequency axis are divided by fours to the sections A, B, C, and the average value every section is determined to provide values of +0.25, +2.5, and -0.5. The frequency data of the intensities close to the average values of signal intensity of the sections A, B, C are reduced. f1, f2 in the section A, f6, f8 in the section B, and f10 and f12 in the section C are removed, respectively. Since the data interval on frequency axis is uneven by the reduction of the data number, the position on the axis of a part or the whole of the frequency data is changed so that the intervals of the remaining data are substantially equal.  The signal intensities of the data after removal and movement are connected to form a power spectrum data.
