a three- wire system has a balanced Y- connected load with a75-Ω resistance, 125- mH inductance, and 55-μFcapacitance in series from each line to the neutral point. assuming positive phase sequence with Vp= 125V at 60 Hz, find the line current, the total power taken by the load, and the power factor of the load
Two amplifiers are cascaded, one with a voltage gain of 6 db and the other with a voltage gain of 4. if 1 V is applied at the input of the first amplifier, what is the voltage at the output of the second amplifier
A number stored in IEEE single precision floating point format has S=0, E=0111 1101, and F=0.1000 0000 0000 0000 0000 000. What is this number in decimal
Design an analog computer circuit (using minimum resistor values of 10 k ohms ) to obtain the summing (adder) function. Vo = -v1 -v2 +v3
A buck converter has input voltage of 10 V, switching frequency 1 kHz, The load resistance of 5 Ω requires average voltage of 5 V with a maximum ripple of 20 mV. The maximum ripple current of the inductor is 0.2 A.
What is the perceived colour if the energy of light is same corresponding to red green and blue,and zero at other frequencies what about red and green frequencies only
Starting from the expression for the MOSFET unity-gain frequency, fT=gm/2*pi*(Cgs+Cgd) and making the approximation that Cgs>>Cgd and that the overlap component of Cgs is negligibly small, show that for an n-channel device fT=3*un*Vov/4*pi*L^2
the solutions at both frequencies about a total transit time of 1000 years (speed of light in a vacuum result) such that subtracting one from the other leaves just the delay that is of order of 1 second.
Given an electronic sensor, measuring the speed and outputing it in voltages, we are asked to design this computer unit. Design an analog computer, getting the speed information from a sensor and returning speed + 3 times the acceleration value to..
Sketch the spectrum of this signal indicating the complex size of each frequency component. You do not have to make separate plots for real/imaginary parts or magnitude/phase. Just indicate the complex phasor value at the appropriate frequency.
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31mV/mm with +/-2cm maximum core displacement.
The forward transmittances of unity feedback tracking systemsare given below. For each, find the type number of the system, the steady state error coefficients k0,k1, and k2 and the steady state errors to unit step ramp, and parabolic inputs.
If you have a 30 VDC - 4A power supply and need to power two 24VDC - 0.8A MFC (mass flow controller), create a circuit that divide the voltage and can handle the power.
