A certain three-port network is lossless and reciprocal, and has S13 = S23 and S11 = S22. Show that if port 2 is terminated with a matched load, then port 1 can be matched by placing an appropriate reactance at port 3.
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.
An AC motor with impedance Z = 4.2 + j3.6 O is supplied by a 220 V, 60 Hz source. Determine the time average power delivered to the load.
What is the maximum angle the shaft can turn?
Assume that when you measure a power supply voltage through a series of 1 Mega Ohms the voltage drops by half compared to the direct measurement. What is the input resistance of the meter
Identify the tank, you need to see what kind of barrel is on the tank - What is the transmission of the receiver path? Why can't the receiver efficiency be greater than 50% on the receiver path?
if 4 cells each rated for 2v, 0.15A connected as batterries in three different ways. find voltage and current rating of each type. (Hint - all in parallel, all in series, two groups of series connected in parallel)
The muons created by cosmic rays in the upper atmosphere rain down more-or-less uniformly on the earth's surface, although some of them decay on the way down, with a half-life of about 1.5 ,u,s
How to design the logic circuit for a room has three doors, with aswitch next to each door, and one over head light. A person shouldbe able to enter or exit from any door and turn the room light onor off by toggling the switch.
assuming a perfect diode, I have a small circut which has three legs joined at the center. One leg has a +12V supply and a 1K ohm resister. Second leg has a -16 Volt supply witha 2K ohm resister, and the third has a perfect diode, with a 4K ohm re..
A 65volt neon lamp is connected across a 8h coil with aresistance of 275. When the coil's field collapses, a 6k resisteris inserted into the circuit in series with the coil. The source is 25 volts D.C.
determine the sum of the incremental cash flows for Alternative B-Alternative A First cost $: A=-50,000 B=-85,000 Annual operating cost/year: A=-8,600 B=-2,000 annual revenue/year: A=22,000 B=45,000 salvage value: A=3,000 B=8,000
Two Loads are in parallel with a 2000 Volt sinusoidal source.Load 1 draws 40 Amps at 0.5 lagging power factor. Load 2 draws 15Amps at 0.8 leading power factor. (a) Make a table showing each load and its complex power
