Q1-2. A continuous time analog signal is represented by x(t)= cos(2000TTT). This signal is sampled at different sampling frequencies with the first sample taken at t=0. a. Sketch the analog signal x(t) for 0 sts 4 ms. b. Sketch the sampled signal for 0 sts4 ms if the sampling frequency is 8Hz. c. Sketch the sampled signal for 0sts4 ms if the sampling frequency is 2Hz. d. Sketch the sampled signal for 0sts4 ms if the sampling frequency is 1Hz. e. From the results of b, c and d, which sampling frequency would yield samples which resembles closely to a? Which sampling frequency would produce the worst result?
