Consider a 3-input function G whose POS form is known to contain
the maxterm X + Y + Z.
1) What is the maximum number of minterms that the SOP form of G
can have such that no simplification is possible? Derive the
corresponding Boolean expression for both SOP form and POS form.
Can G0 be simplified?
2) Let us assume that all minterms that do not exist in the SOP
form of G are “don’t care”s. Can the POS form of F be simplified? If
so, what is the simplified Boolean expression for F?

During a power outage, a homeowner starts a generator that outputs 4,000 W of electrical power. It burns gasoline at a rate of 15 gallons per day.
Gasoline has an energy content of 19,800 BTU/lb, a density of 6.07 lb/gal and a carbon content of 86% by mass.
1. What is the generators efficiency at converting gasoline energy to electrical energy? How many pound of CO2 does the generator emit per day?

By using MATLAB
1. Divide a speech signal or music signal into frames of size N
= 64.
2. Compute the N?point DFT of each frame.
3. Save only first L = 20 DFT coefficients.
4. Reconstruct the frame from these L coefficients. (Do not disturb
the symmetry
of DFT during inverse DFT computation. X[k] = X[N ?k] for real
signals, N = 64
here. Pad zeros for missing DFT coefficients.)
5. Comment on the quality of reconstructed and the original speech
signal.
6. What is the effective data compression ratio? Note that DFT
coefficients may be
complex valued!
7. Repeat the above experiment for L = 10 and L = 5.

A 35 km, 34.5-kV, 60-Hz three phase line has a positive-sequence series impedance z = 0.10 + j0.40 Ohms/km. The load at the receiving end absorbs 15 MVA at 33 kV. Assuming a short line, calculate: (a) the ABCD parameters, (b) the sending-end voltage for a load power factor of 0.95 lagging, (c) the sending-end voltage for the a load power factor of 0.9 leading. (d) For which case is the sending-end voltage higher?

A 2000 V single-phase synchronous generator is being used as a
backup
generator outside a diagnostic center. When the generator
terminals are short-circuited and a field excitation current of 2.5
A is passed, the
ammeter between the terminals read 100 A of full load current. If
the terminals
of the same generator are opened and the voltage across them is
measured using
a voltmeter, we get the value of 500 V with the same excitation
current. The
armature resistance is 0.8 ohms.
Determine the voltage regulation of this generator if it is
delivering 100 A
during normal operation with unity power factor, 100 A with 0.8
leading PF,
and with 0.71 lagging PF.
(Hint: Synchronous Impedance = (0.C Voltage) / (S.C Current))
