How many times is a do while guaranteed to loop?

5. Below which is not a statement from an open loop control system is.... a. Less stable and less preciseb. Harder to makec. Relatively little power requirementsd. Impossible to obtain on an open systeme. stability is not the main problem

Why does crosstalk increase with frequency? Why does it increase rate V? What is excitation? Why is it when pulses are used for excitation the magnitude of crosstalk is determined by rise and fall times(transition times) rather than duration of pulse?

Which statement out of the 5 is TRUE, Explain Why (50 Words) Pulse width modulation (PWM) can be used to control the speed of a DC motor. Whichstatement is correct?1. The ratio of the ON-times (supply voltage) and OFF-times (zero volt) send to theterminals of a DC motor is proportional to the average of the motor acceleration.2. PWM can be used to modulate the magnetic width of a brush-less AC motor.3. PWM modifies the pulses sent to a motor which in turn adjust the motor torqueproportionally to the pulse ratio.4. PWM can be used to adjust the average voltage delivered by a power source.This is achieved by rapidly switching the power signal on and off. Longer on-timescompared to the off times leads to a higher average power seen by the load, e.g., aDC motor.
