    Logisim question -- Simulation of a small logic circuit is not working

    Let's see whether I understand. I create a reset pulse and connect it to the state 00. I also connect the input to the 01 state. I connect a constant '1' to all the Enable's? Is that correct (assuming it's not :-))? Re your question, I would probably use only 4 as I could switch between the...

    Logisim question -- Simulation of a small logic circuit is not working

    You didn't fully read my comment. "001 is the first state (remainder 0), 010 is the second state (remainder 1), 100 is the third state (remainder 2)." It's merely a notation; obviously the first state is 00, second is 01, third is 10, according to the remainder, but this is merely a notation...

    Logisim question -- Simulation of a small logic circuit is not working

    Perhaps this will help. It's certainly relevant and relates directly to the implementation. 001 is the first state (remainder 0), 010 is the second state (remainder 1), 100 is the third state (remainder 2). What I truly need help with is the Logisim implementation. How do I initiate the system...

    Logisim question -- Simulation of a small logic circuit is not working

    I am still not sure I understand. It's expected to be the implementation of the FSM found here: http://www.cs.unca.edu/~bruce/Fall10/255L/Lab5FSM.html This FSM outputs the quotient of x/3. I know that the implementation is correct I simply don't know how to initialize it in Logisim.

    Logisim question -- Simulation of a small logic circuit is not working

    Lewando, how do I set the initial state? How do I assign the initial state to the DFFs? Could you please guide me through?

    Logisim question -- Simulation of a small logic circuit is not working

    That's precisely my problem! How do I set the initial state? How do I assign the initial state to the DFFs? This is my very first attempt at designing something synchronous using Logisim and DFFs; could you please guide me through fixing these issues stymieing it from working properly? I was...

    Logisim question -- Simulation of a small logic circuit is not working

    I am trying to implement the following circuit in Logisim, yet all I get is y=0. Any idea what might be the problem? First image is what I am trying to implement; second it my Logisim attempt which yields 0. I'd appreciate some feedback.

    How to find monostatic RCS of flat strip.

    I have developed all the necessary expressions for finding the desired RCS but am having difficulties applying the approximations. If I included my work here would anyone be kind enough to assist?

    How to find monostatic RCS of flat strip.

    I'd appreciate some help finding the monostatic RCS of a flat strip of length a. I have figured out the necessary expression for the scattered field but am having difficulties figuring out the requisite approximations for arriving at the desired sinc result. If I provided all the expressions...

    Stripline's characteristic impedance

    THIS IS NOT A HW/COURSEWORK QUESTION! I am simply revising for an exam and am trying to better understand the behavior of the stripline as shown in the file attached. What would be the effect on the characteristic impedance, as W/b/epsilon_r/t increases (each separately)?

    Testing the reduction of input to output ripple of MC7805

    Here is all the information I have, quoted verbatim: "An important feature of the 7805 regulator is large attenuation of the ripple between the input and output (i.e., large ripple rejection). We’ll induce very high ripple (using the wave generator, connected to an RC link) and add a 10V DC to...

    Testing the reduction of input to output ripple of MC7805

    You are absolutely right and I'm terribly sorry; I inadvertently left that information out. Here it is -- the ripple chosen here is a sine function of 1.5V/120Hz. Are you able to better answer my question now?

    Calculating MC7805 parameters using datasheet

    I understand how to extract the line regulation and load regulation from the table, but my question was different. I'd like to use the test parameters in the datasheet attached to calculate them (probably using the formulae listed in #1 above). How should THAT be carried out?

    Testing the reduction of input to output ripple of MC7805

    Why would there be no output whatsoever from the MC7805 if I short-circuited C17?
