Homework Statement
Derive the FT for a full-wave rectified sine wave, i.e., |sin(wt)|
Homework Equations
$$1/(√2π)\int_{a}^{b} |Sin[wt]| {e}^{-i w t}dt$$
The Attempt at a Solution
I'm not entirely sure how to start doing this problem. What I tried doing was noticing that both of these equations are even, thus so is their product. So we can change the limits to go from 0 to infinity and multiply the result by two. this doesn't really help much however. I also tried writing the exponential as sin and cosine but that didn't change anything either...
