1. Define standing wave ratio (SWR). What are the standing wave ratios for
(a) an infinitely long line,
(b) a short-circuited line,
(c) an open-circuited line, and
(d) a line terminated by its characteristic impedance?
2. Define line impedance. What is its value for an infinitely long line?
Perform experiments using your circuit design. Using your digital scope, plot (and submit) input voltage and output voltage from your circuit design. Try to vary the filter portion (R, L, C) of your circuit and plot (and submit) output voltages.
When the transformer is switched on (energized), the crest of the inrush current of the transformer can be modeled by an equivalent inductive reactance of 7Ω. Estimate the voltage flicker at the transformer side.
A data transmission system uses messages of duration T seconds. After each message transmission, the transmitter stops and waits Tseconds for a reply from the receiver. The receiver immediately replies with a message indicating that a message was ..
A multi-frequency signal is input to a first-order, low-pass filter. A 60 kHzcomponent is found to be reduced in amplitude by a factor of 90. Find the break frequency of this filter. determine the factor of reduction for the 5 kHzcomponent.
The power factor of a load connected to a 120-V 60-Hz source is raised from 0.866 lagging to 0.966 leading by connecting a 110.5-F capacitor in parallel with the load. Determine the load current I1 and the circuit current IT
When played, it produces a sound of 196 Hz. The wavelength of the wave on the guitar string is 1.28 m. A) What is the tension in the string B) If a speaker is using 25 W of power to produce the sound, what is the intensity level measured at a dist..
1. Calculate the combinational 0-controllability,1-controllability and observability measures for all signals (inputs, outputs, or internal nodes) in a 4-bit ripple-carry adder (RCA).An Example RCA Is shown below:
A continuous line of charge lies along the x-axis, extending from x= +xo to positive infinity. The line carries positive charge with a uniform linear charge density lambda not. What are (a) the magnitude
Two resistors of resistance R_1 and R_2, with R_2>R_1, are connected to a voltage source with voltage V_0. When the resistors are connected in series, the current is I_s. When the resistors are connected in parallel, the current I_p from the sourc..
