WebAnalysis of Fourier series becomes important because this method is used to represent the response of a system to a periodic input and the response depends on the frequency content of the input. Dirichlet Conditions: The conditions that a function f x may be expressed as Fourier series are known as the Dirichlet conditions. Webmore. Step 1: Make a recording of each instrument in digital form. For example, record a single note (A440 or middle-C for example) for 1 second with a sample rate of 20,000 samples/second. Step 2: Perform Fourier transforms on each tone file on a computer to extract the frequency content of each tone. introduction of science fair project
