Care to the values, units and please solve the question step by step in detail. Thanks in advance.


If ?(?) = cos(250??) is sampled with a sampling period of
T=1/200






  1. Plot draft
    x(t) and
    s(t) sampling function (with correct scale) showing
    sampling in time domain

  2. Plot
    X(jΩ) and
    S(jΩ), the CTFT
    of x(t) and
    s(t) respectively with scale and
    show sampling in frequency domain

  3. What is the result of the sampled signal
    xs
    (t) after an ideal low pass filter at half of the sampling frequency?


2) If x(t) = cos (250nt) is sampled with a sampling period of T=1/200<br>a) Plot draft x(t) and s(t) sampling function (with correct scale) showing sampling in time<br>domain<br>b) Plot X(jN) and S(j2), the CTFT of x(t) and s(t) respectively with scale and show sampling<br>in frequency domain<br>c) What is the result of the sampled signal x-(t) after an ideal low pass filter at half of the<br>sampling frequency?<br>
