For each of the indicated voltages, write it as the real part of a complex exponential (v (t) = Re [V est]). Explicitly indicate the value of the complex amplitude V and the complex frequency s. Represent each complex amplitude as a vector in the V -plane, and indicate the location of the frequencies in the complex s-plane.
Consider a 32-bit data bus in a chip. Assume each bit has P0 = 0.2 and P1 = 1 P0 = 0.8 and all the 32 bits are statistically independent from each other. Estimate the power saving when we use the bit-invert technique.
If the emission, factor of producing electric power by PV cells is 100 g of CO2 per kWh, by wind power is 15 g of CO2 per kWh, and by coal is 1000 g of CO2 per kWh, then find the ratio of CO2 emission when a) 15% of power comes from wind farms
question 1 derive the dynamic model and average value circuit of a buck converter assuming the esrs of the inductor and
Calculate the required thickness [in x-direction] of a silicon wafer in nm to create an 0.2 eV energy difference between the two lowest Enx energy states, use mn*= 0.3 x mo with mo = 9.11x10-31 kg. Assume the y and z-direction infinitely long.
Explain clearly what do you understand by super charging. How is it achieved? What is the effect of super charging on the folloing parameters: 1. Power output 2. Mechanical efficiency and 3. Fuel Consumption.
Your boss asks you to contruct a temperature sensorfor measuring the ambient temp outside (-30degreee celcius
A 10-mV signal source having an internal resistance of 200 kO is connected to an amplifier for which the input resistance is 20 kO, the open-circuit voltage gain is 2000 V/V, and the output resistance is 1 kO. The amplifier is connected in turn t..
consider the following systems described by their difference equation. find the transfer function and impulse
A point charge of -2.00 uC is located in the center of a spherical cavity of radius 6.54 cm inside an insulating spherical charged solid. The charge density in the solid is 7.34×10^-4 C/m^3 .
Notice that the circuit does not reset to the start state when an output of Z = 1 occurs. However, your circuit should have a start state and should be provided with a method for manually resetting the flip-flops to the start state.
a DC shunt machine ( 24kW, 240V, 1000 RPM) has Ra= .12 ohms, Nf= 600 turns/pol. The machine is operated as a seperately excited dc generator and is driven at 1000 RPM. When If = 1.8 amps the no load terminal voltage is 240V.
Given two NPN BJTs having β= 100 and ro = 100 Kohm. Using a single 5V dc power supply, design a differential pair amplifier having 1mA bias current in each transistor. What is its maximum gain for linear operation (balanced input, unbalanced outpu..
