Design a 3 dB Lange coupler for operation at 5 GHz. If the coupler is to be fabricated in micro strip on an alumina substrate with r = 10 and d = 1.0 mm, compute Z0e and Z0o for the two adjacent lines, and find the necessary spacing and widths of the lines.
What is the phase relationship between IC and IL at IS minimum. What is the phase relationship between VC and VL at IS maximum.
Design a parallel resonant circuit so that a variable capacitor can adjust the resonant frequency over the AM broadcast band, 535 to 1605 kHz, with Q
Given a resistor of 80-ohm connected to a 12 V battery, find the power absorbed by the resistor. What are the consequences if the resistor is rated at one-quarter watt.
Design a state variable two-pole band-pass filter with a geometric center frequency of 2KHz and a 3dB bandwidth of 20 Hz and the tuning resistances need to be 10Kohms each.
Voltage and current measurement taken for a 3- phase Wye- connected alternator indicate a line voltage of 208 V and a line current of 20 A. What is the value of the phase voltage and phase current
Phase 'A' of a three-phasee 4.16 kV ungrounded system is solidly grounded. For this fault, calculate the magnitude of the positive, negative, and zero sequence voltages at the fault.
A wave in free space has a wavelength of 12 cm. This wave reaches a material in which the transmitted wave has a wavelength of 8 cm. lEl= 10V/m and lHl= 100 mA/m. Find the frequency of the wave, along with the permitivity and permeability of the m..
a flip-flop has a 3ns delay from the time the clock edgeoccurs to the time the output is complemented. What is the maximum delay in the 10-bit binary ripple counter that uses this type offlip-flop what is the maximum frequency the counter can oper..
The samples are binary PCM encoded into n bits whichare transmitted using two waveforms S1 (t)=1.414 sin(w1t) and S2(t)=1.414 sin(w1t) + 1.414 cos(w1t) where t is between 0 and Tb,and the a priory probability of S1 is p(s1) = 0.4.
An incandescent lightbulb rated at 60 W will dissipate 60 W as heat and light when connected across a 100-V ideal voltage source. A 100-W bulb will dissipate 100 W when connected across the same source.
In the digital communication link the data rate is 500 kb/s. The modulator generates the binary FSK signal. a) Determine the transmitted bandwidth if the difference between two frequencies fc1 - fc0 = 300 kHz
