Let x(t) = cos(3/4(t+1/2)+1/4)
a. Determine the frequency, the period of x(t)
b. Given another signal, y(t)= sin(3/4(t+1)+3/8), is y(t) identical to x(t)? Why?
c. Given a discrete time signal x[n] = cos(3/4(n+1/2)+1/4) is it periodic? Why?
Compute the homogeneous solution yh(t). Compute the particular solution yp(t).
Compare a lumped element model of a lossless transmission line (single L and C) with the distributed model. Use the following values for the transmission line in this comparative analysis.
Determine the peak-to-peak current ripple in the output inductor for a forward converter and determine the output voltage ripple of the converter . We know the following parameters: duty cycle d, input voltage Vin, turn ratio: N1/N2
What happens to the propagation delay of the N-bit full adder as N is increases from 2 bits to 32 bits Compare and contrast this method of building an adder with the carry look ahead method described in your textbook
What is the conversion efficiency of an amplifier in which the effective value of the current through a 2.2-k? load is 5 mA and the drain on the 18-V dc supply is 3.8 mA
Find the nonzero value of ω for which the expression for Z(ω) given is purely real. Give your answer as a function of R, L, and C.
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
A DSSS-CDMA signal has a chip sequence that is 1,000 chips in length. The sequence repeats every millisecond. Define DSSS-CDMA Chip Sequence
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
