2) If x(t) = cos (250nt) is sampled with a sampling period of T=1/200 a) Plot draft x(t) and s(t) sampling function (with correct scale) showing sampling in time domain b) Plot X(jN) and S(j2), the...

Please answer all the subparts you can count this question as 2 questions and take my rights these all subparts are connected each other please dont leave just solving first three. Please asnswer the question step by step and please care to explain the question in detailed with your own sentence and explain why you used that formula, calculations etc asap. Thanks in advance.

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