A sinusoidal current has a peak-to-peak value of 15 mA and a frequency of 100 Hz.
(a) Plot this waveform, to a base of time, and
(b) write down the standard expression for the waveform.
1.A shunt-connected DC motor operates at its rated terminal voltage. Its no-load speed is200 radians/second. At its rated torque of 500 Nm, its speed is 180 radian/second. Themotor is used to directly drive a load whose load torque TL depends on its ..

Suppose an engineer is designing an external PCB board with an abnormally large number of programmable devices and is unsure of which protocol to choose for his hardware (DAC s, ADCs,PGAs, and Digital POTS/Trimmers)
a) Determine if the following expression is valid by using a truth table and by using algebraic manipulation: X1X3' + X2X3 + X2'X3' = ( X1 + X2' +X3)(X1 + X2 + X3')(X1' + X2 + X3) b) Use algebraic manipulation to show if x'(y' + z') = x'y' +x'z'
