Question:
The sequence
x[n] = cos (π/4 n). −∞ < n < ∞
was obtained by sampling a continuous-time signal
xc(t) = cos (Ω0t). −∞ < t < ∞,
at a sampling rate of 1000 samples/s, what are two possible positive values of Ω0 that could have resulted in the sequence x[n]?

Teaching was always an area where I can pursue my passion. I used to teach my friends and junior during my school and college life. After completing my professional qualification (chartered accountancy) and before joining my job, I also joined an organization for teaching and guidance to my juniors. I had also written some articles during my internship which later got published. apart from that, I have also given some presentations on certain amendments/complex issues in various forms.
