If the earth is considered to be a metal sphere(radius˜6371[km]), how much charge Q must bedeposited on its surface in order for an arc to be established inthe air. If the earth's surface was charged to the value byremoving all the electrons from a volume of soil, how large wouldthis volume be? Assume that the electron density of soil isapproximately 7 x 1023[cm-3].
Main Memory size is 256K words, Cache size is 16K words block size is 32 bytes Show the mapping in terms of tag, index and block offset for direct map, 4 way set associative, fully associative
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.
The HCS112 SPI is configured for 6 Mbaud. Assuming that it takes 1 microsecond to load each character, how much time is required to transmit 10 characters
The solar constant at Earth orbit (1 AU = 1 Astronomical Unit - Sun-Earth distance) is ~1400 Watts/m2. Assuming that this Poynting flux magnitude can be associated with a single E- and Hfield (i.e., E × H ),
The fourier transform of the triangular pulse x(t) is expressed as: X(w) = 1/w^2(e^jw - jwe^jw - 1) Use this information, and the time-shifting and time-scaling properties to find the fourier transform of the signal: y = x, -1
A two-resistor voltage divider consists of a 10 k and a 15 k ohm resistor, with the 10 k resistor connected to the voltage source and the 15 k resistor connected to ground. If the output voltage is 2.5 V across the 10 k resistor
A 92in*24in*32in, 450kg Square D motor controller is used to drive a 1600 hp,2400V,3-phase,60Hz squirrel-cage motor. a. assumeing the motor has a minimum efficiency and power factor of 96%and 90%,respectively
A three-phase, 60Hz, wye-connected synchronous generator has balanced line-to-line voltages of 480V at its terminals. The generator is supplying power to two balanced and delta connected, three-phase loads. the first load is made up of three.
1) Two signals are said to be orthogonal if the integral of the product of the signals is 0 over one period of the new (multiplied) signal. Assume x(t) and y(t) are orthogonal energy signals with energy, Ex and Ey, respectively.
Implement the circuit with a block diagram decoder (you don'tneed to show the internal implementation of the decoder) and OR gates only. A combinational circuit is specified by the following three Boolean functions
a) Using K-Map, find the minimum product-of-sums for the following function. Circle the term on the map and write the result in algebraic form. b) Draw the block diagram in NOR-NOR.
An AC motor with impedance Z = 4.2 + j3.6 Ω is supplied by a 220 V, 60 Hz source. Determine the reactive power delivered to the load.
