A 300 ohm feedline is to beconnected to a 5-m long, 200 ohm line terminated in a 150 ohmantenna resistor. Both lines are lossless and use air as aninsulating material, and the operating frequency is 30MHz.
Determine
(a) The inputimpedance of the 5-m long line.
(b) The voltage standingwave ratio for the feedline.
(c) A quarter wavetransformer is now used to replace the 200 ohm line. Find thecharacteristic impedance of a quarter wave transformer tomatch the feedline and the resistor.
(d) Calculate the lengthof the quarter wave transformer for the matched case.
(e) Find the inputimpedance seen at the transformer input when operating frequency ischanged to 40 MHz.
(f) Find thereflection coefficient when the frequency is 40 MHz.
(g) Find the VSWR on thefeedline for the reflection coefficient in part (f).

Consider DSB used to transmit an audio signal of 6kHz on a GSM phone with a carrier around 879MHz. By what factor is the Nyquist rate greater if you sample the DSB signal directly rather than the baseband message signal
A 22000 V, 60 Hz generator is connected to the high voltage side of a 22000-2200V, 500 kVA step down transformer. If the resultant core flux is 0.0683 Wb (max), determine: A) the number of turns of wire in the secondary coil.
The results of open-circuit and short-circuit tests on asingle-phase, 25kVA 440V / 220V, 60Hz transformer are as follows: Open-circuit test (primary open-circuited, with instrumentation on the secondary side): 220V, 9.6A, 710W.
