A particular motor operates at 10 revolutions per second when its controlling inpul voltage is 3.7 V. Assume that you are using a microcontroller with a PWM whose output port can be set high (5 V) or low (O V). (a) Compute the duty cycle necessary to obtain 10 revolutions per second. (b) Provide values for a pulse width-and period that achieve this duty cycle. You do not need to consider whether the frequency is too high or too low allhough the values should be reasonable. There is no one correct answer
