| Fourier Transforms are an important mathematical tool and understanding how the Fourier Transform (FT) is applied in chemical instrumentation greatly enhances students' success. However, in most undergraduate curriculums, students are only exposed to the Fourier Transform while learning about FT-NMR and FT-IR instrumentation. Few labs incorporate explicit instruction on FT due to its mathematical content. In “Learning Fourier Transforms using Excel”, sophomores in the Quantitative Analysis Laboratory use Microsoft Excel to gain experience with determining FT output given an input signal, selecting an adequate sampling frequency, and orthogonal functions. The laboratory allows students to quickly recalculate the FT output after making small changes. Students are assessed on five FT related topics: 1) instrumentation utilizing the FT, 2) describing the FT, 3) determining the FT output given an input signal, 4) selecting an adequate sampling frequency and 5) orthogonal functions. |
