**Concept:**

The digital frequency (Ω) is related to analog frequency (f) through the sampling frequency f_{s}.

\({\rm{\Omega }} = \frac{{2\pi f}}{{{f_s}}} \Rightarrow \omega {T_s}\)

**Analysis:**

∵ since analog sampling frequency (f_{s}) is doubled, then the digital sampling frequency

f_{s} = 2f

\({\rm{\Omega }} = \frac{{2\pi f}}{{2f}} = \pi \)
