2. Consider the ideal sampler below, where an input signal x(t) is multiplied by the delta train p(t) En (tnTs). The figure below also contains a sketch of X(jw), the CTFT of x(t). = Let wM be the bandlimit of r(t) and we = = 2π/T, be the sampling frequency. You are also given that x(t) X x8 (t) = x(t)p(t) =Σs(t-nTs) p(t) = n WM = 3ws 4 -WM Figure 1: Ideal Sampling 1 X(jw) WM (Part a) Sketch Xs(jw), the CTFT of xs(t). (Part b) Design and sketch an anti-aliasing filter that you would use to pre-filter x(t) to avoid aliasing. (Part c) Sketch the new Xs (jw) when the input to the ideal sampler is the signal x(t) after passing through the anti-aliasing filter in Part b.
