Q.  The Hilbert transform of the signal sinω1t + sinω2t is
- Published on 15 Oct 15

a. sinω1t + sinω2t
b. cosω1t + cosω2t
c. sinω2t + cosω2t
d. sinω1t + sinω1t

ANSWER: cosω1t + cosω2t
 
In Hilbert transform, the signal gets shifted by 900.

So the signal sinω1t+ sinω2t gets shifted by 900
sinω1(t+900)+ sinω2(t+900)
= cosω1t+ cosω2t
