Abstract:
1. A signal generating apparatus comprising: a data generator which generates a data series in which a plurality of data containing first data, second data, third data, and fourth data are arranged at a predetermined sampling period; a first signal generator which generates a first pulse-width modulation signal in which a pulse is arranged in a pulse period longer than the predetermined sampling period, a time point of a front edge of the pulse being set in response to the first data, and a time point of a rear edge of the pulse being set in response to the second data; and a second signal generator which generates a second pulse-width modulation signal in which a pulse is arranged between the adjacent pulses of the first pulse-width modulation signal, a time point of a front edge of the pulse of the second pulse-width modulation signal been set in response to the third data, and a time point of a rear edge of the pulse of the second pulse-width modulation signal been set in response to the fourth data.
