A three-level PAM system is used to transmit the output of a memoryless equally-likely ternary source whose rate is 2000 symbols/sec. The signal constellation is shown below. Determine (a) the input to the detector, (b) the optimum threshold (to be compared with the detector input) that minimizes the average probability of error, and (c) the average probability of error.
1. Compute the probability of having the sum of 10 by throwing (a) two dice, (b) three dice. 2. What is the probability of three of a kind for a poker hand with (a) a card deck of 52 cards, (b) a card deck of 32 cards
Consider a hollow spherical conductor with total charge +5e. The outer and inner radii are a and b, respectively. (a) Calculate the charge on the sphere's inner and outer surfaces if a charge of -3e is placed at the center of the sphere.
Is connections in transformer are mains connected with the transformer or winding connections If it is mains connections then how can we connect zig-zag transformer in delta configuration
Three friends (Al,Bob and Chris) put their names in a hat and each draws a name from the hat.(Assume Al picks first, then Bob,then Chris). Find the sample space. Find the sets A,B,and C that corresponds to the events "Al draws his own name".
three coins are tossed. Describe the following events: A. at least two heads occur. B. At most one head occurs. C. Exactly two heads occur. D. No heads occur Find the probability for the occurence of each event.
A semiconductor, in thermal equilibrium, has a hole concentration of p0 = 2x10^16 cm^-3. The minority carrier life time = 3x10^-7 s. (Assume, ni = 10^10 cm^-3)
For the equation F(a,b,c,d) = ab'c' + abc'd + abcd + a'bcd + a'bcd', determine all prime implicants and all essential prime implicants: (a) using a K-map, (b) using the tabular method.
Explain an engineering solution for the BP Oil Spill in the Gulf of Mexico. Discuss the impact of the above engineering solution in an environmental context. Do not discuss the environmental impact of the BP Oil Spill.
describe the steps in the procedure based on grid-based color/texture histogram similarity measure for database retrieval of images that closely match a query image.
If the voltage across a capacitor is a square wave, predict the resulting current waveform (draw the voltage and current waveforms). Repeat the process when the voltage across the capacitor is a sine wave.
Sizes are given as the diameter of the pizza in inches. The cost of a pizza is based on the size. Bob would like to know which size of pizza has the lowest cost per square inch. a. Identify the inputs and outputs for this problem.
A delta-wye connected three-phase transformer is rated at 38 MVA with primary and secondary line voltage ratings of 345 and 125 kV, respectively. The transformer p.u. reactance is 10%, the p.u. no-load current is 0.1.
