1. Noise in FTIR Nyquist sampling theorem This is for ideal case
Sample at twice the highest frequency
This is for ideal case
Noise in interferogram can make it difficult to accurately extract frequencies

3. Project Goal
Determine minimum sampling frequencies needed for different levels of noise in a signal to accurately reconstruct the spectrum
Look at the relationship between frequency content and minimum sampling frequencies for a given noise level
Spacing between frequencies in spectrum
Number of frequencies in the spectrum
