余弦波

In addition, since the back electromotive force occurring in an inductance element is cleared to zero during a half wavelength of period of the cosine wave, speed electromotive force can be measured by immediate shifting from a setting period to a measuring period.

另外，由于在余弦波的周期的半波长期间，使在电感元件中产生的反电动势VL清零，通过立即从设置周期转移到测量周期，能测量速率电动势。
