To preface, this isn't a homework question but rather a self-study question to help me to understand the basics of finding the DTFT and magnitude of the DTFT based on a discrete time signal sampled from a continuous time signal.

I was wondering if anyone has any methodology to approaching questions where you're asked to plot the magnitude of the DTFT of a discrete-time signal, when $x(t)$ is sampled according to $x[n] = x(nT_s)$`, with $F_s$ equal to a given value.

For example if $$T_{s}=8W$$$$1/T_{s}=8W$$ and : $$x(t) = T_{s}\frac{1}{4W}\frac{\sin(2\pi Wt)}{\pi t}\frac{\sin(2\pi 2Wt)}{\pi t}$$

What are the first questions that you would ask yourself that will help you to plot the magnitude of the DTFT. I am having trouble translating the DTFT to the plots themselves.
