I have to do the fourier transform of this signal $\left(\frac{1}{10}\right)\operatorname{sinc}\left(\frac{t}{10}\right)$ where sinc function is defined as $\frac{\sin(\pi x)}{\pi x}$.

the transform of this signal according to my studies is: $\operatorname{rect}\left(\frac{f}{\frac{1}{10}}\right)$.is right?

"is it right" - could you show what you did on paper to get your result? –  J. M. Mar 28 '12 at 20:42
    
I had applied rules find in tables in my math book –  Mazzy Mar 28 '12 at 20:44
    
Which book? How did you apply said rules? Even if you have the right answer, that's not worth much if your method is faulty. –  J. M. Mar 28 '12 at 20:46
    
In my book I have a formula says: $Asinc(Bt) \to \frac{A}{B}rect\left(\frac{f}{B}\right)$. I applied it as I found it. –  Mazzy Mar 28 '12 at 20:48
    
So, why didn't you get $\mathrm{rect}(10f)$ as the answer? –  J. M. Mar 28 '12 at 20:51
