Consider the following signalw(t) = 4sinc(400*t)a) What is the minimum sampling rate that can be used to obtain samples that completely specify the signal w(t)?
b)Plot the ideally sampled signal and its amplitude and phase spectra (or if possible the total spectrum) for the signal w(t) above for sampling rates of 300 Hz
c)Plot the ideally sampled signal and its amplitude and phase spectra (or if possible the total spectrum) for the signal w(t) above for sampling rates of 500 Hz
It is given that the energy consumed by a computer system is (100 Joules/sec^2)*t^2 Joules during the first second after being activated at t=0. What is the average power dissipation during this time
The input power to the geenrator is 100hp. When the generator is operating at rated values and unity power factor, the generator is 80% efficient. a.) Find the generator speed in rpm and rad/sec. b.) Find the mechanical torque supplied to the gener..
A 3-phase, 440VAC, 6-pole, 60Hz, wye connected induction motor takes 30KVA at .8 power factor lagging, and runs at a slip of 3.5% at full load. The stator copper losses are 500W, and the rotational losses are 350W.
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
The NMOS transistors in the circuit shown in Figure P16.68 have parameters Kn =0.2mA/V2,VTN =0.5V,λ=0,andγ =0.(a)Forgatevoltagesof φ = 2.5 V, determine the quasi-steady-state output voltage for (i) vI = 0
Sven has decided to make and sell his grandmother's pasta. He rents a building for $600/month and pasta equipment for $300/month. The pasta costs $.20 /pound in raw materials to make . Sven can make up to 3000 pounds a month by himself.
An LVDT with associated signal conditioning will be used to measure work-piece motion from -20 to +20 cm. The static transfer function is 2.5 mV/mm. The output will be interfaced to a computer via an ADC.
The air feels humid. No air is coming from the registers. The air handler is in the attic. An examination of the condensing unit shows that the suction line has ice all the way back to the compressor. The compressoris still running.
Voltage in complex forms, An engine consumes 10kw of power and 4kvar reactive power at a current of (6+j4)Amps
A 3.0 microFarad capacitor is connected in series to 100kohms resistor, a toggle switch, and a 24 V DC power supply. Determine I (t=Tow) and Vr (t=Tow), Vc (t=Tow). Determine I(t=2Tow, Vr(t=2Tow, and Vc(t=2Tow).
(Probability of negative lifetime is negligible) Lifetime of chip 2 is also a Gaussian RV with mean 22,000 and standard deviation 1000 hours. Which is preferred if the target lifetime of the system is (i) 20,000 hours and (ii) 24,000 hours
Design a handheld hair dryer with the following specifications and realistic constraints: 1. It uses a 60 Hz, single-phase, 120 V r.m.s sinusoidal voltage source. 2. It has three settings low, medium, high.
