consider the set of activities, duration (in days), and predecessors for a project given below.Activity A B C D E F G H I J KDuration 9 12 3 4 5 9 8 3 6 9 1Predecessors - A A B,C C B D F,D G H,I E
a) Develop a network diagram representation for the project.b) Determine the critical path.c) Determine he float time for all activities that are not on the critical path.
A temperature sensor has a static transfer function of 0.15mV/degrees C and a time constant of 3.3 s. If a step change of 22 degress C to 50 degress C is applied at t = 0, find the output voltages at 0.5s, 2.0s, 3.3 s, and 9s.
After the user enters the words, the program will determine which words would come first and last if the words were listed in dictionary order. The program must stop accepting input when the user enters a four letter word. Assume that no word is m..
How does a transistor switch compare to a mechanical switch. In other words, a mechanical switch when it is ON has zero impedance. What about the transistor switch.
Consider a uniformly charged sphere of radius R1 with a spherical hole of radius R2 displaced a distance x0 from the center. Let ρ be the charge density. a) What is E on the x axis as a function of x
An electric field of 3.10×105 is desired between two parallel plates, each of area 36.0 and separated by 0.620 of air.What charge must be on each plate?
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
Design a synchronous circuit that implements a 4-bit decade (modulo-10) counter (0000,0001, ..., 1001, 0000,...) a. Fill in a transition table (using don't cares for undefined next states).
Suppose you are given an op amp and 20 resistors, each with resistance R. Assuming ideal op-amp behavior, design a circuit which, given input voltages v1, v2, v3, and v4, will deliver a voltage vo, given by vo = 2v1 + 4v2 -2v3-4v4 to a load resist..
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.
Draw a state diagram for a synchronous sequence detector that will detect every occurence of the sequence 111001 in a serially transmitted message of any length. The sequence detector should detect overlapping sequences as well as individual occur..
120V, 60 Hz source is connected to a distribution line whose resistance, and inductive reactances are 0.1Ohm, j0.2 Ohm, respectively. Single phase, 2HP, 120V, 0.75 lagging pf. motor and 2.4Kw, 120V heater is connected in parallel.
