Abstract:
An amplitude signal and a frequency signal are generated through processing of data. The frequency signal is angle modulated. The amplitude signal is adjusted based on a delay time and is amplitude amplified. The resultant signal from the angle modulation is amplitude modulated based on the resultant signal from the amplitude amplification to obtain a modulated signal. The modulated signal is used to calculate a delay between the amplitude signal and the frequency signal, which is used for feedback control of the delay time by which the amplitude signal is adjusted until no delay exists only in a test period. Through the signal generating, a sinusoidal signal is outputted as each of the amplitude signal and the frequency signal during the test period.
