Three imported wines are to be ranked from lowest to highest by a purported wine expert. That is, one wine will be identified as best, another as second best, and the remaining wine as worst.
a. Describe one sample point for this experiment.
b. List the sample space.
c. Assume that the "expert" really knows nothing about wine and randomly assigns ranks to the three wines. One of the wines is of much better quality than the others. What is the probability that the expert ranks the best wine no orse than second best?
Use two different criteria for determining the effective bandwidth of e^(-t)u(t). Ad the bandwidth, use the frequency at which the amplitude response drops to 1% of its peak value (at w=0). Next use the 99% energy criterion for determine the band ..
A 5 Kg silicon ingot is doped with 10^16 cm^-3 phosphorous atoms. what is the total mass of the phosphorous in the ingot. the atomic mass of silicon and phosphorous are 28.09 g/mol and 31.02g/mol.
The bit energy to one-sided noise density at a PCM receiver input is 30 dB. Referring to the figure above, determine the approximate detected S/N ratio (in dB) for 8-bit BPSK with a matched filter detector.
Why does search in game-playing programs always proceed forward from the current position rather than backward from the goal
If L=0.0053nH, C=15µF find the operating frequency of series LC circuit. What factors decides capacitance? Explain using diagram.
Determine the number of gates needed to implement an eight-bit carry-lookahead adder assuming that the maximum fan-in for the gates is four.
A small gasoline engine can put out 24,000 N-m/min of mechanical power. The engine is used to drive an electrical generator that is 70 percent efficient. 1 N-m = 2.78 X 10-4W-h. Find the output of the generator in Watts.
a) At what time t1/2 have half the atoms decayed b) How many atoms have decayed at t = 40 ns c) Draw a graph of Nexc as a function of time. Show in the graph the lifetime, 1t1/2, 2t1/2, 3t1/2 and 4t1/2.
Why star delta starter is preferred with induction motor? State the difference between generator and alternator. Why AC systems are preferred over DC systems? How can you relate power engineering with electrical engineering? What are the various kind..
When no real time processing is needed the system can be noncausal. Consider the case of averaging an input signal x(n) uner real time conditions. suppose you are given two different filters y{n}= 1/n *(symbol of Sum) x(n-k) on top N-1 at bottom k=..
An object in a microwave oven 25 cm in diameter and 4 cm thick is being warmed. Determine how deeply the signal penetrates if the objects εr is 12.5 and σ is 2 S/m at a frequency of 2.5 GHz. Assume that the plane wave calculations are valid.
