Task 2.2. Sampling (10 marks)

The objective of this task is to generate a sampled i.e. discrete version of 𝑥a(𝑡). Sampling is the process that maps an analog signal to a discrete signal. In keeping with our subscript convention, we will call this digital signal 𝑥d[𝑛]. (5 marks)
Based on the chosen bandwidth in Task 2.1, set the appropriate sampling rate (or sampling frequency) 𝜔s.

Hint: you should use the Sampling Theorem.
For a chosen sampling frequency 𝜔s, a sampling period 𝑇s = 2𝜋𝜔s. Then compute the sampled signal 𝑥d[𝑛] for 𝑛 ∈ [−50,50].
The code will look like:

Plot the sampled signal 𝑥d[𝑛]. Recall that the stem function should be used to plot discrete signals.
