If you have a 300 ohm transmission line terminated with an antenna that presents a (400 ohm - j 600 ohm) load impedance:
Design a synchronous 2-bit, binary, up-counter using the following specification: The counter has five inputs ( not including the clock) and three outputs. The inputs are CLR ("Clear"), LOAD, COUNT, LB and LA.
A sample of radiocactive material undergoes decay such that the number of atoms N(t) remaining in the unstable state at time t is related to the number No at t = 0 by the relation N(t) = No exp(t\tau)
There is a 3 ohm resistor and j4 ohm inductor in series with each other. There is a 4 ohm resistor, a -j13 ohm capacitor, and a 10 ohm resistor in series with each other.These two series circuits are in parallell with each other.
Two ideal diodes are placed in series, pointing in opposite directions. What is the equilvalent circuit for the combination What is the equilvalent circuit if the diodesare in parallel and pointing in opposite directions
Let Un be a sequence of iid zero-mean,unit-variance Gaussian random variables. A "low pass filter" takes the sequence Un and produces the sequence Xn =1/2 ( Un +Un-1) a.) Does this sequence converge in the mean square sense
obtain, via the bilinear transform, the coefficients of a digtal filter that is maximally flat in the passband, 0 to 4 kHz, and has an attenuation of at least 25 dB at frequencies over 10 kHz. Assume a sampling frequency of 32 kHz.
Does the carrier frequency of a system have an impact on small scale fading and shadowing. when moving over a distance x,will variations in received signal power be greater for low frequencies or high freq and why.
Four signals, each having W = 3 kHz, are to be frequency-division multiplexed with 1-kHz guard bands between channels. The subcarrier modulation (modulation to accomplish the FDM) is AM, with one signal left at baseband.
The left and right channels of a analog stereo signal are sampled at a 45kHz with each signal being converted into a digital bit stream using a 12-bit A/D converter. Determine the combine bit rate of the two channels after sampling.
An unspecified resistance, R, and a 12Ω resistor are both connected across a 24V source in parallel. The power dissipated by R is 12W. Determine the value of R and the total power delivered by the source.
Discuss the sequence of actions that occur in the operation of the control system for a traffic light that includes sensors in the roadbed. Indicate which actions are time-driven and which actions are event-driven.
use the method of recursion to solve the following problems: compute y[n] for n = 0,1.2, when x[n] = 0 for all n andy[-l] = 2. Compute y[n] for n = 0,1.2, when x[n] = u[n]and y[-l] = 0. Compute y[n] for n = 0,1.2, when x[n] = u[n]and y[-l] = 2.
