Consider an environment with propagation exponent n = 4. The fading margin between the median and 10% decile, as well as between the median and 90% decile is 10 dB each. Consider a system that needs an 8-dB SIR for proper operation. How far do serving and interfering BSs have to be apart so that the MS has sufficient SIR 90% of the time at the cell boundary? Make a worst case estimate.
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication.
What are two types of variables that can be used for values that exceed 256, and describe what is the difference between the variables, how to declare them and the memory allocated, and the numerical range for both.
Write a 4-bit up counter. Your counter has a asynchronous clear and when the clear is activated, the counter is reset to 3. The count range is from 3 to 9.
Compare the readings of two ammeters of unequal resistance when placed in parallel with each other and the combination inserted in series in a circuit.
A three phase ac machine with sinusoidally distributed windings has a 3-phase inductance, Lm = 40 mH . Balanced three phase voltages are applied to the stator with line-line voltage,VLL = 208V ( RMS ) , at 50 Hz.
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..
a 10 pole 25 cycle alternator directly coupled to, and is driven by a 60 cycle synchronous motor. how many poles are there in the latter
2) Draw the logic circuit for each of the following. For each gate, determine EVEN or ODD parity and find the output for the given input data: a) 4-input XOR, input data=1001 b) 5-input XOR, input data-10010 c) 6-input XOR, input data=101001 d) 7-..
You do some quick measurements and find that the area of the lagoon behind the dam would be about 5m wide by 20m long, and the lagoon would be about 3m deep at high tide, and 1m deep at low tide.
an electric motor operates at 220V rms ,60 Hz, draws 20A rms, and has a power factor of 0.75 lagging. a) what is average power absorbed by the motor b) what value capacitor should be connected in parallel with the motor to give a power factor of 1
A PN junction has a doping concentration of 10^15, 10^16, or 10^17 cm-3 on the lightly doped n-side and of 10^19 cm-3 on the heavily doped p-side. Obtain series of curves of 1/(C^2) vs. V, where V rages from -4V to 0V in steps of 0.5 V.
The lighting and motor loads of a small factory establish a 10kVA power demand at 0.7 lagging power factor on a 208V, 60 Hz supply. Determine the power-factor capacitor that must be placed in parallel
