The optical properties of an absorbing medium can be characterized by various sets of parameters. One such set is the index of refraction and the damping constant. Explain the physical significance of those parameters, and indicate how they are related to the complex dielectric constant of the medium. What other sets of parameters are commonly used to characterize the optical properties? Why are there always "sets" of parameters?
Design an active first-order RC low-pass filter (using a 741 op-amp) with a cut-off frequency of 10 kHz and a band-pass gain of 20 dB. Derive the step response and voltage transfer function.
Using 3kohm resistors and ideal op amps, design a low-passunity-gain butterworth filter that has a cutoff frequency of 20 khz and is down at least 25 dB at 100 khz.
Describe in details the Thévenin's and Norton's theorems. Compare and contrast the above theorems.
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
Bennington Industrial Machines issued 146,000 zero coupon bonds seven years ago. The bonds originally had 30 years to maturity with a yield to maturity of 7.1 percent. Interest rates have recently increased, and the bonds now have a yield to maturity..

A "shift and add" multiplier works as follows: given two n bit numbers X and Y , look at the LSB of X: if it is one, then add Y to the running sum. If it is zero, then don't do anything (since multiplying by 0 is 0!). Next, shift X to the right by..
A heat pump maintains a dwelling at 68 F. When operating steadily, the power input to the heat pump is 5 hp, and the heat pump receives energy by heat transfer from 55 F well water at a rate of 500 Btu/min.
Provide an ideal mixing operation with a 10-kHz local oscillator having an amplitude of 2, and eliminate the undesired component by using a band-pass filter centered at 20kHz. The bandwidth should be sufficient to pass the shifted AM signal.
Estimate the straight voltage gain for the amplifier of Example 3.7
