A 6-pole lap-wound d.c generator has 600 conductors on its armature the flux per pole is 0.02wb.
calculate
(I) the speed at which the generator must be run to generate 300V.
(ii) what would be the speed if the generator were if wave-would?
What assumptions would need to be satisfied for the implementation of Bayes Classifier, Euclidean, Mahalanobis, Parzen windows, Gaussian probability density function, Maximum likelihood parameters estimation of Gaussian pdfs, Naïve Bayes, Guassian..
you have the task of ordering a replacement inductor for one that has become defective. The information on the nameplate has been painted over and cannnot be read. The machine that contains the inductor on 480V at a frequency of 60 Hz.
i) Identify the PSK type and calculate the bandwidth if the modem is transmitting with 9600bps and 2400 baud. ii) Suggest a way to reduce the baud rate to 1200 baud and calculate the new bandwidth.
Give a counterexample to show that the following statement is false: "When the magnetic field through a loop changes, currents run in the loop in such a way as to make a new magnetic field in the opposite direction to the original one."
Gold cost about $100 an ounce in 1971. In 2007, the cost of an ounce of gold is hovering around $800. compute the average price increase for gold.
A BJT differential amplifier is biased to have 500uA dc current in each device, β = 100, RC1 = RC2 = 1Kohm, and RE = 3Kohm. Assume ro = ∞. When operating in balanced in, balanced out mode what is the maximum allowable resistor tolerance
