An a.c. supply of 230V is applied to a half-wave rectifier circuit through transformer of turns ration 5:1. Assume the diode is an ideal one. The load resistance is 300Ω.Find (a) dc output voltage (b) PIV (c) maximum, and (d) average values of power delivered to the load.
The minimum useful bandwidth of the amplifier should range from 10Hz to 100KHZ, and this can be determined by the frequency of vin.The maximum peak value of vin is 0.5V. The specified coupling capacitors(non-polarized) are anticipated to comply wi..
In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB.
Suppose we have a ten-turn square coil 25 cm on each side lying in the x-y plane. A magnetic flux density is directed in the positive z direction and is given by 0.7 sin(120πt) T. The flux is constant with respect to x, y, and z. Determine the vol..
For a RL circuit, write a diffedrential equation in which the only time dependant quantity is current (use Kirchoff's loop). Derive an expression for current, i(t), in terms of L,R, and Vo. If Vo=5V, R=2.5 ohms, L=100 nH
Design and implement a sequence detector using a finite state machine that detects the sequence 1, 1, 0, 1, 0. Consider previous/oldest bits for the sequence detection. Design the fuction using D-Flip-Flop
(a) Find the matched-filter frequency response function H(f) for a perfectly rectangular (video) pulse of duration τ, andamplitude A. (Assume the pulse extends in time from -π/2 to+π/2). (b) Sketch (roughly) its magnitude abs {H(f)} for positive fr..
The armeture leakage reactance is 0.10 per unit on the generator rating as abase. Find(a) the unsaturated value of the synchronous reactance inohms per phase and per unit, (b) the short-circuit ratio, and (c)the saturated reactance in per unit and..
