Abstract
Abstract A method of displaying signals includes the steps of determining display cut-out time intervals from waveform changing times of each of signals based on a predetermined time interval, and displaying the signals based on the determined display cut-out time intervals such that portions of the signals corresponding to the determined display cut-out time intervals are excluded. The determined display cut-out time intervals may be displayed such that portions of the signals corresponding to the determined display cut-out time intervals can be informed. In this case, predetermined patterns may be displayed. The predetermined pattern may be a pattern representing the waveform at the time when each of the determined display cut-out time intervals starts and having a predetermined time length. Alternatively, the predetermined pattern may be a pattern representing the waveform at the time when the corresponding determined display cut-out time interval starts and having a time length corresponding to that of the corresponding determined display cut-out time interval. The color of the pattern may be different from that of the signal.
