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)...
