EE5410 Signal Processing : Inverse relationship between time and frequency domain
1. In the frequency domain, as W increase, X(jw) becomes broader, while the main peak of x(t) at t =0 becomes higher and the width of the first lobe of this signal becomes narrower.
2. In the time domain, an increase in T1 broadens x(t) but makes X(jw) narrower.-- scaling property.
