To produce an 800 Hz sine wave, a four-pole generator must be operated at
A. 200 rps
B. 400 rps
C. 800 rps
D. 1,600 rps
A. Wave A leads wave B by 15°
B. Wave A lags wave B by 15°
C. Wave A leads wave B by 105°
D. Wave A lags wave B by 105°
Duty cycle = (Pulse duration/Total period of signal)*100%
Pulse duration = 15us
Total Period of signal = 1/20kHz =0.00005
So Duty cycle = 0.3 = 30%
