Thanks for that answer. Are there any texts you would recommend that delve deeper into the subject with respect to Data Communication techniques?

I'm having hard time understand what bandwidth really is? The book I'm using defines it as the width of a signal's spectrum (where spectrum is the range of frequencies in a signal). So, for example, I have a composite, periodic signal s(t) = 4/π[sin(2πft) + (1/3)sin(2π(3f)t)]. Then the...

I need to prove that a 3x3 matrix with all odd entries will have a determinant that is a multiple of 4. This is how I set it up: I let A = { {a, b, c}, {d, e, f}, {g, h, i} } with all odd entries then I define B = { {a, b, c}, {d + na, e + nb, f + nc}, {g + ma, h + bm, i + cm} } where I add...
