Derive a minimum-cost realization of the four variable function that is equal to 1 if exactly two or exactly three of it variables are equal to 1; ohterwise it is equal to 0 ?
1. What is the difference between discrete system and digital system. 2. What is "baseband modulation"? What types of baseband modulation are there. 3. How does time division multiplexing work? What factors affect how many channels you can transmit.
determine the time it takes to process the multiplication operation in the binary multipler described. Assume that the Q register has n bits and the clock cylcle is t nanoseconds.
Sketch an sc unit cell with lattice constant a=4 angstroms,whose diatomic basis of atom A is located at the lattice sites, andwith atom B displaced by (a/2,0,0). ASsume that both atoms have thesame size and we have a clse packed structure
A sinusoidal current is zero and increasing at t = -3.33ms; the next zero crossing occurs at t = 6.67ms. a) calculate T, F, and W. b) if i(0) = 25.98 A, Find i(t). c) By what angle does i(t) lead another current i(t) = 5 sin (wt - 5°) A.
Design a 3-tap FIR highpass filter with a cutoff frequency of 1,600Hz and a sampling rate of 8,000 Hz using: a. Rectangular window function b. Hamming window function Determine the transfer function and difference equation of the designed FIR system
Create 2 equations with 2 unknown variables. For example, one equation would be ax + by = c and the other equation would be dx + ey = f where x and y are the variables and a, b, d, and e are coefficients for the variables and c and f are numbers.
A 3 phase, 208V, 4 pole, 60Hz, Y connected synchronous generator has a synchronous reactance of 8 ohm. Assume the resistance of this generator is negligible. The machine terminal voltage is maintained constant at 208V (line to line).
A designer searches for a simple circuit to provide one-third of a signal current I to a load resistance R. Suggest a solution using one resistor. What must its value be. What is the input resistance of the resulting current divider
A 3-phase, 5 MVA, 11 kV, 60 Hz synchronous machine has a synchronous reactance of 10 Ohms per phase and has negligible stator resistance. The machine is connected to the 11 kV, 60 Hz bus and is operated as a synchronous condenser
The number of cell phones recycled or refurbished instead of being sent to landfills is increasing by about 30% per year since 2004. In 2008, 5.5 million cell phones were recycled or refurbished. (a) Find an exponential model for the situation desc..
Calculate: a) the total charge in the device at t = 3 s, assume q(0) = 0 (round to three decimal places) b) the power consumed by the device at t = 1 s (round to three decimal places)
Water moves through a constricted pipe in steady, ideal flow. At the lower point the pressure is 1.69 105 Pa and the pipe radius is 2.80 cm. At another point 2.50 m higher, the pressure is 1.35 105 Pa and the pipe radius is 1.60 cm.
