TWO programs, X and Y were executed in THREE different machines, C1, C2 and C3 with the following outcome of execution times in second respectively; 8, 5; 6, 4; 3, 7. Calculate and determine a) Rela
Because A - B = A + (-B), the subtraction of signed numbers can be accomplished by adding the complement. Subtract each of the following pairs of 5-bit binary numbers by adding the complement of the
The PCI bus found in many computers transmits 64 bits per clock cycle at 33MHz. How does the bandwidth of the PCI bus compare to the serial FireWire (IEEE 1394) serial bus specification, which is 40
Draw a digital circuit consisting of a 2-input AND gate and three inverters, where an inverter is connectedf to each of the AND gate's input and its output. For each of the four possible combination
(i) Draw a diagram of the loads. Determine: (ii) The apparent power (kVA), active power (kW) and reactive power (kVAr) of each of the three loads. (iii) The total apparent power kVA, total active powe
Write a C program that takes as input two lists of integers (in increasing order) and creates combines the numbers in third list of ordered numbers. The two input lists shall be read from separate t
A laser beam traveling through fog was obseved to have an intensity of 1w/m^2 at a distance of 2 meters and intensity of 0.2 w/m^2 at a distance of 3 meters. Knowing that the intensity of an Electro
One superhet, one homodyne, and one that downconverts to baseband receiver is operating in 700-750MHz. Pick a set of IF and LO frequencies, and identify any issues (images, spurs, LO harmonics in r
A standard test for the operation of an FM system is to examine the output spectrum when modulated by a standard test tone. You're examining an FM broadcast tx modded by a 1kHz tone.
Two long parallel wires A and B carry steady currents i a and i b , respectively, in the same direction . The distance between the wires is d. The wires exert forces on each other. Are the force
A copper wire of diameter 1.8mm carries a steady current i of 1.3A. What is the drift speed of the conduction electrons in the wire
The electrical potential at the center of a uniformly charged circular disk of radius R=3.5cm is V0 =550 V. What is the total charge q on the disk
A semi-infinite nonconducting rod is located on the x-axis from x=0 to x=infinity. The rod has a uniform charge per unit length (lamda). Show that the electric field at point P:(0,-R) makes an angle
You have three receivers: a superhet, a direct conversion, and one that downconverts to a baseband signal. You're operating in 700-750MHz. Pick a set of analog IF frequencies and find required LO fr
What is the average power in Watts needed of a machine that cools 10 lb/minute of dry air from 20 to 15 degrees Celsius
A given application written in Java runs 15 seconds on a desktop processor. A new Java compiler is released that requires only 0.6 as many instructions as the old compiler. Unfortunately, it increas
The information signal amplitude is 1.5 V. Determine the carrier frequency and information signal frequency. If the output deviation changes to between 90.002 and 89.998 MHz, calculate the informati
design a bridge reactifier power supply using a 12 volt regulator, that can deliver 12 volts into a 10ohm load. assume a ripple voltage of 10% of load voltage and the drop out voltage of the regulat
A voltage divider consists of two 56kohms resistors and a 15V source. Calculate the unloaded output voltage taken across one of the 56kohm resistors. What will the output voltage be if a load resist
Consider the following function of t, f(t)=1/a[u(t-T0)-u(t-T0-a)]. Here both T0 and a are positive numbers. If you pick some value for T0 and a you discover that you have a rectangular pulse startin
