    Gibbs Phenomenon: Impact on kth Harmonics for Bandwidth Selection

    Ok, so what's the difference if I use 60 terms, which gives me about 99% of the power in the signal versus using 20 terms which gives me about 95% of the power in the signal? When the ultimate goal is to have the smallest bandwidth. I guess the gibbs phenomenon is still present in either case...

    Gibbs Phenomenon: Impact on kth Harmonics for Bandwidth Selection

    How does the Gibbs Phenomenon effect the choice of the kth harmonics for bandwidth selection? Basically, I have plotted a square wave using the Fourier series analysis for choosing the kth harmonics. As, I increase the kth harmonics the oscillations increase. What is the smallest harmonic i...

    Comparing Cell Potentials of ZnSO4/CuSO4 Solutions

    What are the cell potentials of the following? 1) ZnSO4 (1M) & CuSO4 (1M) 2) ZnSO4 (1mM) & CuSO4 (1mM) 3) ZnSO4 (0.1M) & CuSO4 (1M) I tried using the nearst equation and I keep getting that they are all the same value of +1.10V

    Drawing tickets from box - probability

    Oh man! I feel so silly. I got it now. It's always 1-the probability of quitting earlier. Oh man!. Thank you for all of your help. :redface:

    Drawing tickets from box - probability

    Hold on. I think I got it. But how are getting the probability of getting a match to one of three previous cards out of the remaining 5? You have (1/3). I say it is (3/5) because there are three chances of getting a match to anyone of the three cards..

    Drawing tickets from box - probability

    The probability of stopping at the third draw is 2/6? So the probability of stopping at the fourth draw is (1-2/6)? So this times the probability of getting a match to one of the first three cards out of the remaining five is (3/5)? But (2/3) * (3/5) is 2/5. But the answer in the back of the...

    Drawing tickets from box - probability

    The probability of stopping at the fourth draw is, again, the probability you haven't stopped in the first three (1-6/7)?, times the probability of getting a match to one of the first three cards out of the remaining five (3/5)?. I'm am a little confused on how to calculate the probability I...

    Drawing tickets from box - probability

    The probability of stopping at the first draw is 0. (because you have only drawn one ticket). The probability of stopping at the second draw is 1/7 (because out of the 7 remaining cards their is only 1 possibility for a duplicate of the first). The probability of stopping at the third draw is...

    Drawing tickets from box - probability

    Homework Statement A box contains 8 tickets. Two are marked 1, two are marked 2, two marked 3, and two marked 4. Tickets are drawn at random from the box without replacement until a number appears that has appeared before. Let X be the number of draws that are made. Make a table to display the...

    Voltage controlled dependent current source

    I had a question. When you have a circuit with a independent current source and a voltage dependent current source. And the dependent current source is dependent on the Voltage drop across the independent current source. How do I solve for this voltage drop when the currents are in parallel...

    Kirchoff's Voltage Law: Circuit Troubleshooting Help

    Ok I used the loops ad, be, dg, ef. All going clockwise from the node. to get 4 equations and I set them equal to zero. however, from those four equations. you can't solve for any unknown variable. Please let me know if this is solvable as I have tried several different ways and can't come...
