A plane wave in air with an electric ?eld amplitude of 20 V/m is incident normally upon the surface of a lossless, nonmagnetic medium with Xr er = 25.
Determine the following:
a.) reflection and transmission coefficient
b.) standing wave ratio
c.) average power densities of the incident and transmitted waves.
An EKG signal is contaminated by 60-Hz noise. Design a bandstop filter to remove this noise while limiting distortion of the EKG signal. Sketch the magnitude and phase response.
A person shuffling across a dry carpet can be approximately modeled as a charged 100-pF capacitance with one end grounded. If the person touches a grounded metallic object such as a water faucet, the capacitance is discharged
A 300-km bundled 500-kV, 60-Hz, three-phase completely transposed overhead line has three ACSR 1351-kcmil conductors per bundle, with the bundle spacing 0.5 m. The horizontal phase spacings between bundle centers are 10, 10, and 20 m.
Consider the router diagram in Figure 3. Consider that the packets shown are uniformly 500kB in size and that they are all stored in the input buffers of ports W, X and Y. These packets marked with the output buffer they are destined for.
State Carson's rule for bandwidth estimation. What does it reduce to for NBFM and WBFM and d erive an time domain expressionfor the output xd(t) of the system
The exponential Fourier series coecients for a signal x(t) are: ak= { 1.57 when k=0, 0 when k is even and k doesnt equal 0, ((-1)(k-1)/2)/k when k is odd} Determine the following: (a) Plot the spectrum of the Fourier series.
A 78oham lossless planar line was designed but did not meet a requirement. What fraction of the widths of the strip should be added or removed to get the characteristic impedance of 75oham
When a color palette is used to reduce its storage requirements, what is the maximum number of rows in the LUT to keep the compressed image size (LUT + index values for each pixel) smaller than the original image size
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
The capacitor in an RC circuit (R=10.0k Ohms and C=25.0uF) is initially uncharged. Determine the charge and current flowing in the circuit at 0.40 time constants (t=0.40 tau) after the circuit is connected to a 9.00 V battery.
Consider a network with a driving-impedance Z. (1) Find expression for P and Q. (2) Find p(t) in terms of P and Q. (3) Suppose that the network is a series RLC. Interpret the result in part (2).
encounter a sequence of birds while walking in the park. The birds can either be blue (B) or red (R). We let X be the random variable corresponding to the number of birds we encounter until seeing the first blue one.
