Hilbert Transform of signals

Q2. The Hilbert transform of the signal sinω1t+ sinω2t is


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

Correct Answer: b) cosω1t+ cosω2t

Explanation :

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
