Confusion with Fourier Transform and Step Function...clarification needed please :)
I am required to find the Fourier Transform of (without integration):
s(t) = 1 for 0 < t < 4; -t/2 for 4 < t < 6.
I understand that for:
s(t) = t for 0 < t < 1; 1 for t > 1
that this is the same as...
fourier series - trig and complex not matching!?!
i am given a signal which can be written as:
s(t) = -1 {-1 < t < 0}, 1 {0 < t < 1}, 0 {1 < t < 2} [it's a pulse train]
the period, T, is 3.
i have calculated the trig. fourier series representation, which in matlab turns out to be...
Homework Statement
The symmetrical scissors truss is supported at point A and D. The support at D is a rocker bearing and does not produce a horizontal reaction. A, B, C, D, E, & F are pin joints. The members of the truss are not joined to each other where they cross. At A, the angle...
