a. Sketch or use the computer program of your choice to produce a plot of the impedance magnitude versus angular frequency for a 20-mH inductance in series with a 50-μF capacitance. Allow ω to range from zero to 2000 rad/s and the vertical axis to range from 0 to 100 +Ω.
b. Repeat with the inductance and capacitance in parallel.
The unknown input impedance of a horn antenna operated at a frequency of 300MHz is measured using a slotted transmission line and a Smith Chart. When the antenna is connected to the slotted line, the VSWR on the line is measured to be 4
A consumer protection agency conducts opinion polls to determine the quality (excellent, good, fair, bad) of products imported. if the agency conducted a poll in wich 1000 randomly selected individuals were contacted by telephone.
Explain why a voltage follower implemented with an op-amp is a useful circuit component. Explain how the nature of KCL allows the connection to a single op-amp input of multiple voltage signals, each through a resistor, to perform a summing functi..
Find and graph the convolution of two signals. find the Fourier transform and other signals & system related topics using MATLAB.
Draw a constellation pattern for a modern that uses eight equally-spaced phase angles and equally spaced amplitude levels. If the modern operates at 4800 baud, what is its bit rate.
Determine the I/O difference equation relating the input x(n) and the output y(n) for the following LTI systems with the impulse response: h(n)=(0.4)u(n)+(-0.4)^n u(n), where u(n) is the unit step sample signal
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
Determine the nominal reactive power rating of the capacitor bank.
A power factor correction capacitor bank, with negligible resistance, draws a current of 625 amperes whenconnected to its 480 VAC, 60 Hz source. Calculate the capacitive reactive power of the capacitor bank.
In the absence of any special knowledge of network conditions, the typical approach is to pick an arbitrary value, such as 3 s, and hope that this will converge quickly to an accurate value. If this estimate is too small, TCP will perform unnecess..
An AM signal has a carrier frequency of 3 MHz and an amplitude of 5 V peak. It is modulated by a sine wave with a frequency of 500 Hz and a peak voltage of 2 V. Write the equation for this signal and calculate the modulation index.
Consider a point to point link needs a beam which is directed asclose as possible to the other antenna. This will minimizeinterference between different communications systems, as well asmaximizing the power transfer on a given link.
