1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms.
2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
Finite Difference Time Domain (FDTD) numerical method to develop for me a software program that simulates - evaluates Specific Absorption Rate (SAR) Distribution in a Human Head Near a Mobile Cellular Phone as a student project.
Discuss how the angle of the incident light affected the solar cell? How could solar cell designs and/or installations be designed to counter this affect?
What are the four characteristic parameters of transmission line? Which parameter is used to calculate the real loss? Which parameter is used to calculate the charging current? Which parameter is almost negligible and why?
Do either or both of the reasons you gave in part (a) above also apply to a point to point voice link using frequency modulation? c. Which parameter of an FM transmission determines whether it is wideband or narrow band?
draw a combinational logic circuit (using AND, OR, etc.) that implements the function. (Note: x is a multiple of 3 if x=i*3 for some integer i.)
Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)
Show that the power in a three-phase, three-wire system with balanced loads is constant at every instant. Deduce an expression for the power in terms of the line voltage, line current, and the power-factor.
Determine the standing wave pattern for the voltage in the line. Express the result in real insantaneous form and simplify
The base class must also have a virtual print() function that displays the class name. Randomly assign print functions in three other classes that display the class name. Create 7 pointers of the base class and have them point to all the classes.
An analog signal xa(t), band-limited to 5 Hz, is sampled at a rate of 10 samples per second to give a discrete-time signal x(n) = xa(0.1n). The discrete-time signal x(n) is then filtered with an digital FIR filter, h.
Explain briefly from what you notice about the digital output values in (a) why a digital output value of an A/D converter is rarely the exact same digital value as the analogue input value.
A three-phase overhead transmission line has a per-phase resistance of 0.15 ohm/km, and a per-phase inductance of 1.3263 mH/km.
