    Converting Drums to Keyboard: Can it be Done?

    Hello, Is it possible to 'convert' the sound of a drum to a keyboard instrument, e.g. using signal processing techniques. Measure the pitch of a snare drum, and attempt to recreate it in MATLAB? I don't think it's possible, since a (snare) drum doesn't have a fundamental frequency, does...

    Overcoming Math Education Challenges to Pursue Higher Studies

    Not really in 2unit mathematics, more so in 3unit and 4unit maths. I should've taken them, but my ego wasnt really good!

    Overcoming Math Education Challenges to Pursue Higher Studies

    Is this the same as 'Discrete Mathematics'? http://www.maths.usyd.edu.au/u/UG/JM/MATH1004/Resources.html

    Overcoming Math Education Challenges to Pursue Higher Studies

    Hi I am a third year electrical engineering undergraduate, who would also like to engage in higher study of mathematics. I am in awe of mathematics, having done linear algebra and calculus as part of engineering, plus whatever is necessary for elec engineering (Laplace, DE's, Fourier, complex...

    How Can a Coffee Company Maximize Profit Using Linear Programming?

    Homework Statement Question (to be solved graphically) ------- A coffee company sells coffee under a "Best blend" label and an "Economy blend" label. Both are blended from three basic grades of coffee: Best blend = 40% A + 40% B + 20 % C Economy = 20% A + 40% B + 40% C The market...

    Why Is the Electric Displacement Field Important in Understanding Capacitors?

    Can someone please post a problem/situation outlining the motivation / usefulness of the electric displacement field? (Particularly with a capacitor) I'm having trouble understanding the concept and information is sparse on the internet.

    Density of States Confusion

    Why do electron states split into bands in solids if states exist for electrons that have the same energy level

    Density of States Confusion

    "the density of states (DOS) of a system describes the number of states at each energy level that are available to be occupied. " But I thought there can't be more than 1 electron in a state? How does DoS have any meaning when dealing with eleectrons?

    How can I use direct integration to solve for the convolution of two signals?

    THat's the thing, when I put it into the integral I have to work out a bunch of inequalities that really makes my head spin. This question is so much harder than the example :(

    How can I use direct integration to solve for the convolution of two signals?

    Hey guys, I'm having trouble doing ct convolution i'm trying to convolve two signals together ie, the input x(t) and the impulse response h(t). basically, knowing the impulse response of an LTI system, you can find out the response y(t) to any arbitrary input x(t) using the convolution...

    Calculating Resolution of Space Camera for Imaging Earth

    yeah, I'm having trouble figuring out how I can get that very small airy disc size to correspond to resolution on the Earth's surface, 100km's away. I tried using this where di is distance to the image from the lens, and do is distance to the object. But, then I get a very small number and if i...

    Calculating Resolution of Space Camera for Imaging Earth

    So I'm looking for a dimensionless number? Not sure what it could be, I'm only given lens diamater, focal length and wavelength.
