Compute the power absorbed by an element in a circuit, but for a simple sinusoidal current i = sin(2πt/T) where T = 1 s.
(a) Assume that Ohms law holds and R = 5 ohm.(b) Assume that Ohms law does not hold and that voltageand current are related by the following nonlinear relationship:V = (5i - 1.25i^3).
The resistance per 304.8 m of copper wire uses in the extension cord of AWG 14,12,10,8 and 6 are 2.58,1.62, 1.02, 0.64 and 0.41 respectively. Assume a 2% allowable voltage drop. Show all working .
Write a brief explanation of the principles of the super-heterodyne receiver. It may help to use a simple block diagram to express the process. Explain the purpose of the Intermediate Frequency amplifiers,
algorithms to show the differences in the intra prediction in the h.264 and hevc coding standards. it should indicate how the intraprediction in the two coding standards makes a difference in their efficiency.
Describe the charge diffusion and drift in a PN junction, without and then with an applied voltage
The frequency response of an FIR filter is H(ejw)=b0+b1*e^-jw+b2*e^-2jw. In each case below, state whether the filter is highpass, lowpass, bandpass or band stop and draw the pole zero plot.
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
What is the energy in joules stored in the capacitor below, The capacitor is shown with 10 volts on each side of it (plus on the left of the capacitor, - on the right), and C = 20 microfarads.
Calculate the required thickness [in x-direction] of a silicon wafer in nm to create an 0.2 eV energy difference between the two lowest Enx energy states, use mn*= 0.3 x mo with mo = 9.11x10-31 kg. Assume the y and z-direction infinitely long.
What are the transfer function and the impulse response of the system?
Calculate the value of vL developed across a 300 H coil when the instantaneous rate of change in component current equals 500 mA/s.
A load has a 20 ohm resistor and a 4 Henry inductor connected in series. It is connected to a power source with v(t) = 100 cos(50t), connected in series to the load. What is the impedance of the load? Use phasor transform methods to obtain your an..
