The switch in Figure has been open for a long time and is closed at t = 0. The circuit parameters are R = 50 Ω, L = 250 mH, C = 0.5 μF, and VA = 1000 V.
(a) Find the circuit differential equation in iL(t) and the initial conditions iL(0) and vC(0).
(b) Use Laplace transforms to solve for iL(t) for t ≥ 0.
a high power FM station of frequency 96.9 MHz has an antenna height of 1200 feet. If the signal is to be recieved 60 miles from the station, how high does the listener need to mount their anntena in this fringe area
Consider the first-order linear differential equation y(t) + 5 (dy(t) / dt) = x(t) Compute the zero-input response (general solution of the homogeneous equation) to find the system-specific part of the response
the current through a .2 μF capacitor is a rectangular pulse with an amplitude of 2 mA and a duration of 4 ms. Find the capacitor voltage at the end of the pulse when the voltage at the beginning is -2V.
It is required to use a peak rectifier to design a dc power supply that provides an average dc output voltage of 15 V on which a maximum of 1-V ripple is allowed. The rectifier feeds a load of 150 ohm.
Using the results of your program, Calculate the entropy of a source that outputs the 26 English characters with the probabilities you calculated.
In a game, half of the (large) pool of potential opponents are beginners, a third intermediates, and one sixth are masters. Your chances of beating them are 60% for beginners, 30% for intermediates, and 10% for masters.
What happens when you have a non-zener and zener diode in series opposing each other eg non-zener is forward bias and the zener is reverse bias assuming both are ideal (infinite slopes when they are operating).
Calculate the small-signal voltage gain at the two ends of the range.
design a one input one output serial 2's complement. the circuit accepts a string of bitsfrom the input and generates the 2's complement at the output thecircuit can reset asnchronously to start and end the operation
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs at least 100 mA.
A stabilization circuit has a stability factor of 0.04 and an internal resistance of 5 Ω. The unstabilized voltage can vary between 75 and 100 V, and the load current can vary from 40 to 80 mA. Determine the maximum and minimum values for the stabil..
