WebMay 22, 2024 · Example 4.2.1: Finding the Fourier series coefficients for the square wave sqT(t) is very simple. Mathematically, this signal can be expressed as. sqT(t) = {1 if 0 < t < T 2 − 1 if T 2 < t < T. The expression for the Fourier coefficients has the form. ck = 1 T∫T 20e − (i2πkt T)dt − 1 T∫T T 2e − (i2πkt T)dt. WebStep 1: Make a recording of each instrument in digital form.
