MEEN 260 Introduction to Engineering Experimentation Homework 8: Sampling Theory and the Nyquist Frequency Assigned: Thursday, 26 Mar. 2009 Due: Thursday, 2 Apr. 2009, 5:00pm Learning Objectives: After completing this homework assignment, you should be able to: 1) Determine the Nyquist Frequency based on a sampling frequency 2) Determine if a harmonic signal will be aliased, and the aliased (apparent) frequency of the reconstructed signal 3) Determine the digital signal after sampling an analog signal, including the digital frequencies 4) Reconstruct an analog signal from a digital signal Homework Problems: Problem 1) Nyquist Frequncy a) What sampling frequency produces a Nyquist Frequency of 256 Hz? b) A waveform contains harmonics of 75 Hz. Which of these can be accurately measured assuming the sampling frequency from part a)? (definition: a harmonic is based on integer multipliers of a fundamental frequency) c) An engineer wants to measure vibration effects in a motorcycle engine that redlines at 9500 rpm. Assuming this is also the limit of the frequencies present, what is the minimum
