A voltage generator is connected to the input of a lossless line short-circuited at the far end. The frequency of the generator is varied and the line voltage and line current at the input terminals are monitored. It is found that the voltage reaches a maximum value of 10 V at 405 MHz and the current reaches a maximum value of 0.2 A at 410 MHz.
(a) Find the characteristic impedance of the line.
(b) Find the voltage and current values at 407 MHz.
Let the input to a singly-balanced mixer, f(t), be given by V0 Sin (2 pi fs t). The local oscillator input p(t) is a square wave, alternating between 0 and +1 volt. The freqency of the square wave is 10 MHz, while for the input, fs is 100 KHz.
A small gasoline engine can put out 18,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 80 percent efficient. 1 N-m = 2.78 X 10-4 W-h. Find the output of the generator in Watts.
A beam of X-rays with a wavelength l of 0.15 nm is directed at a crystal whose planes have a spacing of 0.25 nm. How many diffraction peaks (each arising from a different order n) are possible
Usually, transformers are designed to operate with peak flux densities just below saturation of the core material. Why would we not want to design them to operate far below the saturation point? Far above the saturation point? Assume that the vol..
Convert the source into the phasor domain and then do a source transformation into a current source in parallel with an impedance.
A sample of non-ideal gas is made to undergo an expansion process during which its pressure and volume are related as shown in the table below. The energy of the gas at the start and finish of the process is measured and found to be 5 and 3.2 Btu
A 150-kVA, 2400/240-V single-phase transformer has the following parameters: R1 = 0.2 ; X1 = 0.45 ;R2 = 0.02; X2 = 0.0045 ;Rc = 1000 ; Xm = 1500. The transformer is connected to a 150kVA load with 0.8 power factor lagging.
Design an electronic circuit that counts metal objects moving in counter/Conveyor and display the number of objects in the counter.
What is the use of the carry output in a parallel load counter If l have a 3 bit binary parallel load counter do l connectthe count input,and the outputs (Q) from the three flip flops
