    3 Sampling and aliasing The aim of this part is to demonstrate the effects of aliasing arising from improper sampling. A given analog signal z(t) is sampled at a rate fs = 1/T, the resulting samples (nT) are then reconstructed by an ideal reconstructor into the analog signal rat). Improper choice of f, will result in different signals ra(t) + (t), even though they agree at their sample values, that is, tanT) = x(nT). The procedure is illustrated by the...

    Problem 1 (10 points). The time history data in many mechanical engineering measurements are of recorded using a digital data acquisition system so they can be transmitted, stored, and anal easily. The signal is sampled discretely over a duration of Tr (seconds) with a constant time interval of & (seconds) between adjacent discrete data samples. So the signal in the frequency domain is also discretized with the maximum and minimum resolvable sampling frequencies fmax and Jmin being given as 1/(28)...
