A load ZL = 40ohms is connected to a transmission line with Z0=65ohms.
A. What is the reflection coefficient of the load?
B. If a quarter-wave transformer is inserted between the transmission line and the load, what shall be the characteristic impedance Z0 of this quarter-wave transformer in order to realize an impedance match?
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
A PPL multiplier transmitter is to operate with a 915 MHz output. With a divide factor of 64, what value of crystal is needed
How do the short length and medium length transmission line models differ and why Draw the equivalent circuit of a medium-length transmission line
A detector with charge collection time of 150 ns is used with a preamplifier whose input circuit can be represented by the parallel combination of 300 pF and 10,000 ohms. Does this situation fall in the category of small or large collection circui..
A 2.67-F and a 4.20-F capacitor are connected in series across a 25.0-V battery. A 8.24-F capacitor is then connected in parallel across the 2.67-F capacitor. Determine the voltage across the 8.24-F capacitor.
An 8-kg plunger is released from rest in the position and is stopped by two nested springs; the constant of the outer spring is k1 = 4 kN/m and the constant of the inner spring is k2 = 12 kN/m. If the plunger is released from the height
A point charge of 16 nc is located at Q(2,3,5) in free space and a uniform line charge of 5nC/m is at the intersection of the planes x = 2 and y=4. If the potential at the origin is 100V, find V at (4,1,3).
An unbalanced Wheatstone bridge circuit has resistance arms of 400, 40, 602, and 6000-ohm taken counterclockwise around the bridge. The galvanometer has a resistance of Rg=110-ohm and is connected between the junction of the 40 and 602-ohm resisto..
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
The output capacitor in a certain resonant converter sees the net current equal to 40cos(50,000 pi t) A. What value of capacitance will be needed to keep the voltage variation below 5V peak-to-peak
In the early days of Op Amps, banks of Op Amps were used for computing mathematical expressions. Describe how you would configure them to do, say a complex calculus function. Feel free to share a diagram.
Given a four-volt peak to peak square wave, calculate the mean-square error in approximating the wave by only its fundamental sinusoidal component. Assume the average value is zero (no DC offset).
