PROBLEM TO BE SOLVED: To provide a signal generation device that can reduce the number of wires for an input pulse signal and generate an output pulse signal having a pulse width which is equal to or less than that of the input pulse signal.SOLUTION: An output pulse generator (510) detects eight timings from the combination of the level of one input pulse signal out of input pulse signals (INA, INB) output from isolators (IS1, IS2) and the rising and falling timings of the other input pulse signal. The output pulse generator (510) selects every two timings from the eight detected timings to select four pairs of timings, and allocates the four pairs of timings to toggle timings of output pulse signals (SH, MH, SL, ML) to generate output pulse signals (SH, MH, SL, ML).SELECTED DRAWING: Figure 6 |
