    Help to stregnthen laplace and second order diff eq beckground

    Homework Statement Here is my issue. I am an EE student that has been part time for almost five years. I took diff eq and signals a long time ago. I am currently taking a feedback and controls class, and my lack of memory in these topics is killing my study time. I am looking for relevant...

    Why is my state machine output being synthesized away?

    sorry for the delayed replies. I used a different compiler, and everything came out fine. I would like to addres the questions that were asked though. I made a horrible mistake of posting the wrong version of the code, and that is why is does not match the state diagram. To...

    Help with VHDL Serial Port for Automated HVAC Thermostat

    Ok. I had a VHDL class last year, and I have muscled through a project that I started on my own, but now I am a bit stuck. I implemented an automated HVAC thermostat that will moniter each room individually. Each room had a 4 bit parallel input that was muxed into a state machine. The set point...

    Why is my state machine output being synthesized away?

    I also get a warning stating that input x does not drive logic. the code is correct to my understanding. Could this maybe be the compiler?

    Why is my state machine output being synthesized away?

    10 is a don't care input. I have attached a pdf of the state diagram. Also, I want three separate iterations of this to be selected from a three bit input. Could I do case statements for entire state machines? thanks ahead of time. actual output is wrong...sorry. the real problem is that the...

    Why is my state machine output being synthesized away?

    This is my first state machine that has an input large than one bit. The simulation tool says that I synthesize my output away. I think I understand why, but don't really know how to fix it. library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_unsigned.all; -- entity trimoore is...

    How to Simulate a Permanent Magnet on Steel Using Quickfield?

    Hello all. In pursuit of my senior project ideas, I need to simulate a permanent magnet on steel. One of my professors gave me the link to quickfield, but I am a bit confused on how to do this. He said he wouldn't have the time for awhile to help. Do any of you know how to get this simple...

    Calculation of magnetic field

    Although effective, I need the calculated portion to relate to a prototype. I am using extreme examples in my last post to get a point of what I trying to describe across. I will determine when the field is at a unusable point. let's call that "0" It could be 1800 gauss. I just need to get a...

    Calculation of magnetic field

    I need to use the formulas. None of the five online calculators that I have found agree, and also, I will need to graph the field density at an angle from the poles. I want to make a graph of the field. Picture a Round (coin shaped) magnet on a table of steel. The coils will pass from the...

    Calculation of magnetic field

    I have been working on a generator. I would like to double check the "guidelines" given to me. I need to calculate the magnetic field density and stregnth at given distance away from the magnet surface (pole). I also need to calculate B as they decay to the side. I have circular magnets...

    C/C++ Solving C++ Function Calling Error in Code

    That is it! I figured it out on my own, but it is good to see that I didnt just tmake it work by some improper loophole. I have the whole thing finished now. The last part is to write a stub program. I have never done that before. I am assuming that I could give the user an option for a "self...

    C/C++ Solving C++ Function Calling Error in Code

    I could really use some help by seeing this done properly. I will then be able to match some verbage up too. I found the lack of prototype as soon as I posted. How do I make this a function, and not a variable? Please bear with the lack of understanding.

    C/C++ Solving C++ Function Calling Error in Code

    Hello, I have been pretty good with this stuff...but this is the umteenth time I have run into this error. I have gone around it by just using the direct function in the code, but I really really want to master this function calling. My compilation error is always term does not evaluate to...
