## Homework Statement

How can i find the magnitude spectra of 2sin(4000*pi*t)*sin(46000*pi*t)

## The Attempt at a Solution

im not sure how to go about this question, can someone please give me some help on what i should do. I know that for a square wave i can find the fourier series coefficients of it by finding the fourier transform of one period (which is the fourier transform of standard rect function) and then use G

_{n}= f

_{0}G

_{1}(nf

_{0}). But this question im not sure if i can do this shortcut method.

please help, thanks.
