A. Two machinery options are described below. Calcuate the present value of each of the items specified. Assume an interest rate of 6% and a useful life of 8 years. Show all the necesary work to calcualte value.
Option1 = The inital purchase proce of the machine $25000. The salvage value at the end of the useful life will be $5000. Maintenance cost are $2000 first year and increase 0 per year.
Option 2 The machine is leased for an initial payment of $2000 plus annual payments of $3500. There is no savage vakue. A maintenca contract is purchase for a single payment of $10000 at the start of the lease period.
B. What is the equivalent annualized total cost,over the 8 years lifetime, for the machibe with the lowest present value of lifecycle cost.
Suppose we had connected at the input to channel 0 a circuit of the type that attenuates all frequencies above 50 Hz at a rate of 6 dB/octave. What will we then see in the output when we apply 4960 Hz at the input
A coaxial line is filled with a very slightly lossy material with a relative dielectric constant of 5 The line would have a characteristic impedance of 100 ohm if it was air-filled. (a) What is the characteristic impedance of the dielectric-filled li..

What is the inverse Laplace transform of 32/s(s^2+64). Please show all work.
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
A Si PIN photodiode has an i-Si layer of width 20 µm. The p+ layer on the illumination side is very thin (0.1µm). The PIN is reverse biased by a voltage of 100 V and then illuminated with a very short optical pulse of wavelength 900 nm.
a. Evaluate X(s) and specify its region of convergence. b. Determine the values of the finite numbers A and t0 such that the Laplace transform G(s) of g(t) = Ae^âˆ'5tu(âˆ't âˆ' t0)
