A transmission line having a 50 ohm characteristic impedance is to drive a load of 200 ohms.(a) What is the reflection coefficient if the line is connected directly to the load? (b) What is the standing wave ratio on the main line under the conditions of part (a) above? (c) In rectangular form (numerical values required to nearest 0.1) what is the input impedance of a λ/8 section of 50 ohm line connected to a 200 ohm load? Include a figure showing the configuration having the input impedance to be calculated. (d) What is the input impedance of a λ/4 section of 50 ohm line connected to a 200 ohm load? Give answer in rectangular form. (e) What is the input impedance of a 2λsection of 50 ohm line connected to a 200 ohm load? Give answer in rectangular form.
find the complete functions, p(t) and w(t) supplied by the element, not just a number, and graph p(t) and w(t). Choose appropriate intervals of time for your graphs. Assume that both v(t) and i(t) are zero for t
A -find the dc collector current and the dc voltage at the collector. B Replacing the trasistor by its T-model, draw the small signal equivalent circuit of the aplifier. Analyze the resulting circuit to determine the voltage gain vo/vi.
The Dinorwig pumped storage hydroelectric facility in Northern Wales utilizes an abandoned slate quarry named Marchlyn Mawr as the upper reservoir. 600 meters below the Llyn-Peris lower reservoir can be found. The plant contains six 288MW generato..

Explain the following terms; (i) critical radius of insulation. (ii) economic lagging thickness.
Use Microsoft Excel to compare costs from at least three different vendors and reasons to accept specific bids. (May use graphs in Excel to provide a better visual comparison)
The DC machine rotates at 1500 RPM and it delivers rated current at rated terminal voltage. The field winding is connected to a 120 V supply. Find the value of the field current and the value of R (field control resistance) required.
a digital channel is described by 16 QAM, the data rate is 50 Mbps, the bandwidth is 200 MHz, the power is 1 W, and the received noise level is 50 mW. Resolve for SNR, Baud Rate and the Max theoretical bit rate for the channel.
The input to a certain filter is given by Vin(t)=2cos(10000pi*t-15deg) and the steady state output is given by Vout(t)=5cos(10000pi*t+25deg). Determine the (complex) value of the transfer function of the filter for f=5000 Hz.
When one push button is pushed, the selected soda is dispensed and the machine returns to its initial state. One other feature is that an LED comes on to warn the user that two quarters are not available for change, so if a second $1 bill is inser..
Write an equation for the following sequence (use only 3 variables for the right-hand side): The overflow indicator V will turn on iff X is negative, Y is positive and D is positive, or if X is positive, Y is negative and D is negative.
