A certain op-amp has an open-loop gain of 80,000. The maximum saturated output levels of this particular device are when the dc supply voltages are If a differential voltage of 0.15 mV rms is applied between the inputs, what is the peak-to-peak value of the output?
Convert the image to gray scale.
It the resistors used are not ideal but have a ±5% manufacturing tolerance, what are the extreme output voltage and resistances that can result?
Explain the operation and application of the impedance transforming property of an ideal transformer.
The switch in the circuit(b) shown below has been in position A for a long time. It is moved to position B at time t=0. Find Vout(t) for t>0.
An AM modulator is operation with an index of 0.4. The modulation input is m(t) = 4 cos(3πfmt) + 2 cos(5πfmt) + 4 cos(7πfmt) (a) Sketch the spectrum of the modulator ouput showing the weights of all impulse functions.
A current of 2.5 A when flowing through a coil produces an mmf of 675 At. Calculate the number of turns on the coil.
4-pole , 500 volts shunt motor has a simplex lap winding placed in 80 solts , each cotain 30 conductors . The shunt filed resistance and the armature resistance are 250 and 0.005 ohm respectively . the flux per pole is 0.001 webers
Let x(t) be a signal with x(t)=0 for t
Assume Vcont can vary from 0 to VDD. Prove that the voltage drop across the loop filter resistor reaches roughly 1.6πVDD if no second capacitor is used.
Design a digital notch filter to reject frequency 5 kHz completelyand to have a sharp recovery on either side of 5 kHz to a gain ofunity. The highest frequency to be processed is 20 kHz.
The output is 1 when the pattern abca has occurred an even number of times in x(0,t). Give a state description of the system. Use a state vector approach and a minimum-number-of-states approach.
Derive a minimum-cost realization of the four variable function that is equal to 1 if exactly two or exactly three of itsvariables are equal to 1; otherwise it is equal to 0.
