An LTI (linear, time invariant)instrument has the following impulseresponse:h(t)=[2*e -2t -e -t] *u(t)where u(t) is the unit step function
Compute the system's transfer function and the solution of the differential equation when the input x(t)=2 *u(t).
The current through a 8 mH coil changes at the rate of 3.5 A/s. Determine the voltage that appears across the inductor. (mV)
A charge of 4 micro-Coulomb is applied to the surface of the car. If the car travels a distance of 2 meter between the two electrodes, and if the mass of the car is 200 grams, then what is the approximate time taken by the car to reach the second ..
An automobile battery is charged with a constant current of3.75A for5hours. The terminal voltage of the battery isv= 11 + 0.5tVfort> 0, wheretis in hours.(a) Find the energy delivered to the battery during the5hours
An induction motor has an output or shaft power of 30 kW at 86% efficiency. For this operatingcondition, stator copper loss = rotor copper loss = core loss = mechanical rotational losses. Determine the slip.
Use the fact that x = 2 and y = 0 at t = 0 to determine the appropriate value of the arbitrary constant in the solution set.
The woofer can be modeled as a series R-L low pass filter. Suppose that a given woofer has an inductance of 750 micron Hertz and a resistance of 4 Ohms. At what frequncy (in Hertz) does its frequncy response
A collimated light beam from a helium-neon laser at 632.8 nm wavelength impinges on a dielectric film of refractive index of 2.0 at an angle of 75 degrees to normal, with a polarization at 45 degrees to the plane of incidence.
Current, voltage, and power to a three phase system are measured and found to be 20 A, 550 V and 10.5kW respectively. Determine equivalent circuits per phase as follows: (a)wye connected series combination of resistance and reactance in each phase.
For a mixture of ethane 60%, acetylene 20%, and benzene 20% total mass of 250 kg is loaded into a reactor obeying the Carnot cycle, we want to know which produces more work when reacted with 25% fuel, 60% O2, 15% CO2 for 30 cycles.
Calculate Vout (f0), Vout (3f0), Vout(5f0), and Vout(7f0) of the frequency spectrum of a triangle wave (A = 10 V and T = 1 ms) passed through a low-pass R-C filter (R = 10 k-ohm and C =5 nF).
A thyristor is triggered by a pulse of train of 5kHz.The duty ratio of the pulse train are 0.5. If allowable average gate power is 100W, calculate the maximum allowable gate drive power.
The difference in voltage (Bat A - Bat B) should be displayed on a +5V - 0 -5V meter. Each volt on the meter display should correspond to 10 mV of battery difference. Include your choice for all components and power supply voltages.
