Question:
The Fourier spectra of a signal x(t) is shown below. Determine the Nyquist sampling rates for signalsa. x(t)b. x2(t)c. x(t) cos(120 Πt)
Design a network realization of the transfer function below. Show the location of Ii and where the outputVo is taken. Also label all of the network element values. Vo / Ii = H s /(s+2)(s+4)
A 0.2 kg plastic cart and 20 kg lead cart both roll without friction on a horizontal surface. Equal forces are used to push both carts forward a distance of 1 m, starting from rest. Is the kinetic energy of the plastic cart greater than, less than..
For the following voltage and current phasors, calculate the complex power, apparent power, real power, and reactive power. Specify whether the pf is leading or lagging.
Point charge in a conducting shell. A point charge +q is located inside a very thin conducting spherical shell halfway between the center and the shell shown in Figure 5.46. Assume the conducting shell is at zero potential.
Description of Transformer, An 11 kV to 415 V transformer has a rating of 100 kVA. The winding resistance and leakage reactance when referred to the secondary are 0.0142 Ohm and 0.0569 Ohm respectively
A particle having charge q and mass m, initially at rest, is accelerated through a potential difference V0. Find the final speed (assume nonrelativistic).
A digital transducer has 80 cut-outs. It is used tomeasure the speed of a motor shaft. Output signal frequency is800Hz. Find out the motor shaft speed
Calculate the input reactive power of the motor after p.f. improvement. Calculate the capacitive reactance per phase of the capacitors connected in star across the motor.
A belt is wrapped around a pulley creating a torque of 186 N-m. What power is being transmitted if the pulley is rotating at 200rpm
[Computer] Make plots similar to Figure 16.5 of the standing wave (16.18) for several equally spaced times from t = 0 to τ, the period. Take 2A = 1 and k = ω = 2π.
The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted.
A circuit contains two devices that are connected in parallel. If the resistances of one of these devices is 12ohms and the resistance
