Question: 1) Describe how multiplexers are used to build switching circuits.2) Explain the advantages of using threshold gates to construct switching circuits. Illustrate this by using threshold gates to construct half and full adders.
A current source of 12 cos 2000t A, a 200-ohm resistor, and a 0.2-H inductor are in parallel. Assume steady-state conditions exist. At t = 1 ms, find the power being absorbed by the (a) resistor; (b) inductor; (c) sinusoidal source.
For the circuit below, when R1 = 1KΩ, R2= 2KΩ, RL = 4KΩ, and gm = 1 mA/V, what is the voltage gain vo/vsig ?
Write technical details of a wind turbine that employ direct-drive wound rotor synchronous generator (WRSG) and full power converter (Type 4 WECS).
Representing all signals using regular binary code, calculate 16 + 15 and check whether the result is valid.
The global radiation at the solar noon on a summer solstice in Albuquerque, New Mexico (latitude 35° N) is 60mw/cm^2. Assume that (a) 30 % of this irradiance is diffuse radiation and (b) the ground surrounding a PV module is non-reflecting
A 110 pF capacitor and a 440 pF capacitor are both charged to 2.2 kV. They are then disconnected from the voltage source and are connected together, positive plate to positive plate and negative plate to negative plate.
500W lighting is connected in parallel with an inductive load. A clamp-on ammeter reveals a total circuit current of 7A. What is the inductance of the load connected in parallel with incandesent lights. Assume a voltage of 120v and 60hz.
Determine the change in closed-loop gain, Af = Vo/Vi, for the two feedback circuits. - Which feedback configuration will result in less distortion in the output signal?
The electronics industry has experienced profound changes in the last couple of decades.- Can you name and describe some of the most important technological changes that have occurred in the last years?
Using the algorithm defined by, generate N = 50 pairs of zero-mean Gaussian random variables with σ2 = 3 and ρ = 0.6.- Repeat for N = 5,000. Comment on the results.
A helical spring is fabricated by wrapping wire ¾ in. in diameter around a forming cylinder 8 in. in diameter. Compute the number of turns required to permit an elongation of 4 in. without exceeding a shearing stress of 18 ksi. G = 12 × 106 psi.
