Identify one emerging technology, and evaluate its future prospects by identifying the cultural and social factors that may prevent or promote its successful application. Use concrete details to support your answer.
A discrete-time signal x[n] is periodic with period 8. One period of its DFT harmonic function is {X[0],...,X[7]}={3,4+ j5,- 4 - j3,1+ j5,- 4,1- j5,- 4 + j3,4 - j5}. (a) What is the average value of x[n] (b) What is the signal power of x[n]
Design a circuit that will multiply the input voltage by +12. That is the output voltage is 12v1 where v1 is the input voltage. All resistors should be at least 12ohms.
A long straight metal wire of radius r1= 2.20E-2 m is surrounded by a metalic cylindrical shell of inner radius r2= 1.24E-1 m and outter radius r3= 1.91E-1 m. The axes of the wire and the cylindrical shell coincide.
Use Microsoft Excel to compare costs from at least three different vendors and reasons to accept specific bids. (May use graphs in Excel to provide a better visual comparison)
The average power used by the resistor is what you pay to the electric company, but there is also reactive power for which you do not. The complex power supplied to the circuit is defined as: P = ½ V s I*
Design a synchronous counter with the following repeated sequence:2-4-6-1-3-5. Build the counter with T flip-flops and minimized gates. Assume the (active low)asynchronous clear is tied to a logic 1.
Pulse width modulation (PWM) is used to control dc voltage to an electric heater. The supply voltage is 12 Vdc, and the heating element is modeled as a 1 resistance. (a) Calculate the average power delivered to the heater when the voltage is switche..
Given the following function in product-of-sums form, not necessarily minimized, F(W,X,Y,Z) = (W + X' + Y')(W' + Z')(W + Y), Re-express the function in the canonical sum-of-products form. Use little m notation.
Asssume that you are to design a synchronous TDM carrier to support 30 voice channels using 6-bit samples and structure similar toT1.Determine required bit rate
how to determine the sensitivity of junction depth to changes in furnace temperature by calculating (dxj/xj)/(dT/T) for a drive diffusion.
Find the electric potential at point (0,0,z) resulting from a surface charge density ps existing on the z=0 plane from p = a to p = b. Assume V = 0 at an infinite point distance from the origin.
What RF bandwidth must the radio link provide if the modulation is binary phase shift keying (BPSK)?
