a signal x(t) is transmitted through a distortionless lti channel with a time delay of 12 msec. the energy of the output signaly(t) is related to the energy of the input signal by Ey/Ex =.04determine the transfer function H(w) of the system and express y(t) in terms of x(t)
Using Euler's relation , the signal x(t) defined above canbe expressed as a sun of complex exponential signals using the finite Fourier synthesis summation. Determine values for f, N and all the complex amplitudes, a.
A stack controller is a digital circuit in a computer that implements last in firstout (LIFO) storage for temporary data. It operates analogously to a stack of plates where you can put a new plate on the top of the stack or you can take a plate of..
A load is drawing 10 A rms when connected to a 1200 V rms supply running at 50 Hz. If the source is operating at a lagging PF of 0.9, calculate (a) the peak voltage magnitude; (b) the instantaneous power absorbed by the load at t = 1 ms
A manufacturer specification sheet lists the transfer function of a pressure sensor as 45±5% mV/kPa with a time constant of 4±10%. A highly accurate test system applies a step change of pressure from 20 kPa to 100 kPa.
1. a nichrome wire 12 ft long and .011 inch diameter conducts 1.83A when 120v are applied. what is the resistivity of nichrome 2. Copper windings of an electric motor at room temperature of 25 degrees C has resistance of .20(r).
a filamentary conductor carrying current I in the z direction extends along the entire z axis. At z=0 it connects to a copper sheet that fills the x>0 and y>0 quadrant of the xy-plane. Set up Biot-Savart law and find H everywhere on z axis.
A coil of 2000 turns surrounds a flux of 5 mWb produced by permanent magnet. The magnet is suddenly withdrawn causing the flux inside the coil to drop uniformly to 2 mWb in 1/10 of a second. What is the voltage induced.
A 4 pole DC generator has an armature winding containing a total of 648 conductors connected in 2 electrical parallel paths. If the flux per pole is 0.321 x 10^6 Maxwells and the speed of rotation is 1800 rpm.
A disk drive has a constant failure rate and an MTTF of 4,000 hr. What will the probability of failure be for 2-year of operation
Design a hand warmer with a heated element consisting of an encapsulated resistor to be held in your hand and powered by a 6V battery that you put in your coat pocket. Use 26 gauge wire to connect the resistor to the battery.
The ac voltage that is supplied from a wall plug to the incandescent light is 170V sin[(377 rad/s)t]. If the current flowing through the light is 350 mA sin[(377 rad/s)t], determine the power that the light is consuming.
