Joshua Manski EEE 304 – Lab 3 Sampling, Aliasing and Equalization using LabVIEW Dr. Cihan Tepedelenlioglu October 29 th , 2009 Assignment 1 1.1 When the Sampling Frequency is fixed at a certain point and the input signal frequency is adjusted from 0 to 2000, the input signal and the output signal will not only be the same when the Fundamental Frequency is less than half the Sampling Frequency. For the case where the Sampling Frequency is 2000Hz, Aliasing does not occur when Input Frequency (Fundamental Freq) <1000Hz. 1.2 When the Input signal is switched to a square wave, the Frequency response behaves different than a sin wave. In the below figures we show the FFT transform in linear (Left) and dB scale (Right) for a set Input and Sampling Frequency.

Due to the square wave, the Sampling Frequency must be much larger than the Input Frequency in order for the sampled signal to match the original. 1.3
