Two microstrip transmission lines are used to fabricate a parallel resonance circuit at a frequency between 1GHz and 2GHz. The relative dielectric constant of the printed circuit board (PCB) is 4 and the microstrip lines have a characteristic impedance of 80W. The length of the microstrip lines are 30mm and 45mm, respectively.Determine the exact resonance frequency if one of the microstrip lines is short circuited and the other is open-circuited.
Compare a lumped element model of a lossless transmission line (single L and C) with the distributed model. Use the following values for the transmission line in this comparative analysis.
Determine the energy uses on farms in middle east and determine whether or not it is better to use a stand alone system or a grid connected system for the application on farms.
For the system represented by the following difference equation y[n] = 0.5x[n] + 0.5x[n - 1] find: (a) the transfer function H(z) of the system. (b) the frequency response H(e^jw) of the system.
A 500kVA ,7200-240V, 60Hz, transformer with 2.2% impedance was severly damaged as a result of a dead short across secondary terminals. Determine a) The short-circuit current;
an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and deviation of f=20 KHz. A narrowband FM generator with Fc=200 KHz and adjustable deviation f in range of 9 to 10 Hz is available.
Can you confirm-The outputs of two"NAND" gates are connected to the inputs of an "EXCLUSIVE OR" gate.Each of the "NAND" gates has one input at logic high level and the other input
Calculate the value of vL developed across a 300 H coil when the instantaneous rate of change in component current equals 500 mA/s.
A stream can represent many different kinds of sources and destinations, including disk files, devices, other programs, and memory arrays. Discuss how to use the different data stream classes to move data to/from files.
Write and test a C program that outputs a waveform that switches from 10.0 kHz with a 50% duty cycle to 25.0 kHz with a 5% duty cycle every 5 seconds. Your code design must be modular - initializations and program operations are to be performed
The total charge that has accumulated on the positive plate of a capacitor varies with time. The charge follows q=At^2 for the first 4s. a) Find the value of current at t=2,6,9,12,16 s. b) Sketch the current i(t) as a function of time
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a inverting configuration with dual supplies (+5v and -5v) bei..
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
