    Converting Analog Signals to Digital: A 2-bit A/D System

    Okay, that makes sense. Now if I was using signal levels a through e only: ~The range would be from 0 to 10 and have 4 zones. ~Thus 10/4 = 2.5 ~00 is 0-2.5 ~01 is 2.5-5 ~10 is 5-7.5 ~11 is 7.5-10 If that is all correct then the answer would indeed be A because: a=00 b=01...

    Converting Analog Signals to Digital: A 2-bit A/D System

    Obtain the digital words corresponding to the indicated analog signal levels, a through j, as shown in Figure P8.38, that would be assigned by an A/D system with 2 bits. http://img256.imageshack.us/f/eehmrw1.png/ a. None of the above b. a=11, b=01,c=10,d=01, and e=01 c...

    Comparing Bandwidth: PCI Bus vs. FireWire (IEEE 1394)

    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 400 Mbits per second? a. The FireWire serial bus is better. b. The PCI bus is better. c. They...

    What does setting a high baseline mean for design generation and selection?

    My group is currently working on design generation and selection. We have a just about all of it done and ready to go but we are unsure what the professor means by baseline. Here is what he wrote about it: Baseline refers to a set of design variables or expectations that you judge/compare...

    Engineering Basic Circuits - Thevenin's Thm explanation

    I've read through a ton of material and still do not quite understand it. The way that we were taught was: 1) Redraw, with load removed 2) Redraw, find Voc 3) Redraw, find Rth 4) Redraw, using TEC with removed load Most of my questions involve finding Voc and Rth. I understand the steps...

    Engineering (mechanical) drawing probs

    Louisiana State University (LSU) - Required course for mechanical engineers. The only "drawing" course we are required to take. I'm guessing they are wanting us to at least be able to understand engineering drawings even if we are not the one having to draw them.

    Volumes of Revolution: Revolving about a vertical axis

    Homework Statement Find the volume of the solid obtained by rotating the region under the graph of y=1/x and y=1/x^2 about the vertical axis x=-1 Also given are points on the y-axis (0,2) and (0,5). I guessing these points are specific sections of the graphs where we find the volume...
