Design a filter with lower frequency cut-off: 10Hz, upper frequencycut-off: 2KHz, gain of 5, and an input resistance greater than 5kOhms.
A discrete-time signal x[n] is periodic with period 8. One period of its DFT harmonic function is {X[0],...,X[7]}={3,4+ j5,- 4 - j3,1+ j5,- 4,1- j5,- 4 + j3,4 - j5}. (a) What is the average value of x[n] (b) What is the signal power of x[n]
A shunt DC motor has RA = 0.7-ohm and VT =429.6 V. For an output power of 50.4 hp, we have nm = 1,452 rpm and IA = 110.8 A. The field current remains constant for all parts of this problem. Find the rotational power loss in watts.
A series-connected dc motor has RF+RA = .6 ohmns and draws IA = 40 A from the dc source voltage VT = 220 V, while running at 900 rpm. What is the speed for IA = 20 A Assume a linear relationship between IA and phi.
Use rail voltages of +/-15V. Sketch the circuit diagram and the voltage transfer characteristic (Vout vs Vin) Discuss how you chose the values of the components and comment on how accurately you think you can achieve the specification.
The amount of three phase power to be delivered in ‘kW' is equal to the total number of letters in your name (first name +last name) and the single phase power is 10% of three phase power. Assume same power factor for both types of loads.
Design and sketch a current source that delivers 1uA to a load. The sum of all resistors used should be
An RLC circuit exists, with current flowing counter clockwise through it. R= 5.661 Ohms, L=20.2 mH, and C=157.6?F. Voltage across the capacitor is positioned so that the current meets the positive terminal first.
To understand this, imagine we paint one of the blades of an airplane propeller so that we can identify it from the other blades. We will then turn the propeller at 33 rotations per second, in a clockwise direction.
A network has an input impedance of 120+100j Ohm what is the capacitance that should be placed in parallel with the network to provide an input impadance with: a) Zero Reactance at w=1000 rad/s b) Zero Reactance at w=2000 rad/s
A function f has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Derive the truth table for f. (b) Write the canonical sum-of-products expression for f.
A dc motor has an armature resistance of 0.2Ω and an armature inductance of 5 mH. It is driven by a power converter of gain, kPWM = 100 . Design a controller for the armature current loop such that the crossover frequency is 2 kHz and the steady st..
Specify the range required for the control voltage VGS and the required transistor width W. It is required to use the smallest possible device, as limited by the minimum channel length of this technology (Lmin = 0.18 μm) and the maximum allowed v..
