Assume that you are adding two 4-bit numbers. What does a carry-out (in the fifth place) indicate? Does this carry-out indicate something different when we add two positive numbers, a positive and negative number, or two negative numbers?
a radio antenna operating at 1.5 MHz has an input impedance of 6+j226 ohms. A capacitor is connected in series with it for tunning purposes. compute the valur of capacitance needed to tune the antenna to resonance.
calculate ratio of the area to volume for unit cube, a unit sphere inscribed inside the cube and as right cylinder inscribed inside the cube.
A president, secretary, and treasurer are to be chosen from a group of 10 senior members of the IEEE student chapter at the Citadel. Assume that each member cannot serve more than one position.
Submit an excel spreadsheet with your characterization results, and a screen shot of you amplifier schematics, and your simulation result running a sin wave (Use a vsin for input).
A source X produces symbols A, B, C, D, and E with probabilities 0.5, 0.25, 0.125, 0.0625 and 0.0625 (a) Find the information content of X. (b) Give a fixed length code for X. Compute its efficiency. (c) Derive a Huffman code for X
A 2.5 meter long elastic cord is fixed at both ends. a) If the cord is vibrated at a frequency of 35-Hz, a n=3 standing wave is produced. with what speed do waves travel across the cord.
Explain briefly why a capacitor can block DC voltage. How might you use this feature in a design. Explain why the impedance Zeq of a parallel RC circuit decreases as the frequency increases.
A current of 4 A flows through a wire forming a "loop" circle of radius r. If the magnetic field in the center of the "loop" is 10 A, what is the radius along the "loop": a) if the loop consists of a loop of wire, b) if the "loop" consists of 20 t..
A continuos-time system is given as a differential equation: y''(t)+2y'(t)+3y(t)=x'(t)+x(t-2) a. Compute the Transfer function H(s) of the system. b. Compute the Impulse Response h(t). c. Compute the Step Response g(t).
The Problem: An Electric Heater is connected to a constant 250-V source and absorbs 1000 W. Subsequently, this heater is connected to a constant 210 V source.
A transmission line has the following per-unit-length parameters: L = 0.5 H/m, C = 200 pF/m, R = 4.0 /m, and G = 0.02 S/m. Calculate the propagation constant and characteristic impedance of this line at 800 MHz. If the line is 30 cm long
A JFET has the following ratings: gm0 = 4000µs at VGS off ( ) = 6 Volts and gm0 = 2000µs at VGS off ( ) = 2Volts. The component is used in a common source amplifier with values of RD = 3.3 Kohm, RL = 4.7 K ohm,and VGS = 750
