Design a digital notch filter to reject frequency 5 kHz completely and to have a sharp recovery on either side of 5 kHz to a gain of unity. The highest frequency to be processed is 20 kHz.
using 1/(s+2)(s+4) + c find when the poles are repeated and use that value to calculate the impulse response using laplace transforms. Calculate the step response when c = 10 using Laplace transforms.
A ¼ watt resistor has a resistance of 3.2KW what is the maximum current that the resistor can handle. If the wattage rating is doubled, will the maximum current double.
A particle ( charge = 50 µC ) moves in a region where the only force on it is an electric force. As the particle moves 25 cm from point A to point B, its kinetic energy increases by 1.5 mJ. Determine the electric potential difference. ( Vb - Va )
Draw a state transition diagram for a state machine that reads in a sequence of binary digits, one at a time, and stops when it has read in five 1s (need not be consecutive). To "stop" the machine, merely have it orbit in the state
Design a buck converter that has an output of 12 V from an input of 18 V. The output power is 10 W. The output voltage ripple must be no more than 100 mV p-p. Specify the duty ratio, switching frequency, and inductor and capacitor values.
A 10 kW laser beam pointing at the ship is turned on at t=0. What speed the ship will attain in 1 day assuming that the surface of the ship is perfectly reflective and perpendicular tot the beam.
Determine the corner frequencies and the limiting horizontal asymptotes of a common-emitter circuit with an emitter by pass capacitor. Consider the circuit with the parameters Re=4kΩ,Rc=2kΩ,Rs=0.5kΩ,Ce=1μF,v+=5v,V- =-5v.
Use decomposition to find the minimum gate input cost, multiple level implementation for the functions given, using AND, OR, NOT, XOR gates: a) F(A,B,C,D)=sigma(m)(5,6,7,9,10,11) b) G(W,X,Y,Z)=sigma(m)(5,6,7,9,10,11,14,15)
The tuning capacitor of a Wien bridge oscillator is 100 pF and the frequency is 5 kHz. To what value of capacitance pF should the capacitor be changed to if the frequency is to be changed to 2 kHz
A 300 W resistor is connected across the 300 Wantenna input of a television receiver. The bandwidth of the receiver is 6 MHz, and the resistor is at room temperature (20oC). Find the noise power and noise voltage applied to the receiver input.
A bank of induction motors cosumes 36kW at 0.78pf lagging from a 60 Hz 240V RMS line. If 200μF of capacitors are placed in parallel with the load, what is the new power factor of the total load
A machine produces photo detectors in pairs. Tests show that the first photo detector is acceptable with probability 3/5. When the first photo detector is acceptable, the second photo detector is acceptable with probability 4/5.
