Two 5 H inductors connected in series are subjected to an electric current that changes at a rate of 4.5 amps per second. How much voltage will be dropped across the series combination?Now suppose that two 5 H inductors connected in parallel are subjected to the same total applied current (changing at a rate of 4.5 amps per second). How much voltage will be dropped by these inductors?Hint: the total current is divided evenly between the two inductors.
The solar constant at Earth orbit (1 AU = 1 Astronomical Unit - Sun-Earth distance) is ~1400 Watts/m2. Assuming that this Poynting flux magnitude can be associated with a single E- and Hfield (i.e., E × H ),
Compare the noise floor in dBm with the GSM system (BW= 200 kHz) used by the European cell standards (available today in the US thru the AT&T acquired from the Cingular systems) assuming the same noise figure (NF) of 10 dB for the same receivers.
A Fabry-Perot interferometer is to be used to resolve the mode structure of a He-Ne laser operating at 632.8 nm. The frequency separation between the modes is 150 MHz. The plates are separated by an air gap and have a reflectance of r^2=0.999.
A dc shunt motor of 50 hp, 250 V is connected to a 230 V supply and is drawing an armature current of 200 A, and is running at speed of 1200 rpm. Its armature resistance is Ra = 0.2 ohms.
Find the inverse z-transform, x(n), of the following functions by bringing them into a form such that you can look up the inverse z-transform from the tables. This will require some algebraic and /or trigonometric manipulation/calculation.
Design an RC-Low Pass Filter with cutoff frequency at fc=0.5GHz and plot its frequency response and design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
the discrete-time systems, where y[n] and x[n] are, respectively the output and the imput sequences, determine whether or not the system is (1) linear, (2) causal, (3) stable, and (4) shift-invariant: y[n] = x[n+3];
Compare and contrast transmit and receive diversity. Describe how each diversity type lead to an improvement in system performance.
Build a 5-Bit Adder with the following specifications: Must include the Carry Look Ahead Technique. Must be able to add the 2's complement of B to A, when a subtraction is made.
What is the peak frequency deviation of the FM signal and bandwidth of the FM signal? The signal is received with CNR = 30.0 dB. What is the SNR of the recovered video signal at the radio receiver output?
