Web22 Jul 2009 · Luckily, it is possible to calculate the DFT exactly for this special case of an ideal square wave. The result is relatively simple. The amplitudes of all the even harmonics (e.g., 2 GHz, 4 GHz, 6 GHz) are all zero. It is only odd harmonics that have values. The amplitudes, A n, of the odd harmonics are given by: Equation 2-3 where: mats montgomeryWeb10 Nov 2016 · If your sampling frequency is 20,000 Hz and you have a square wave of frequency 500 Hz, this basically means that you will have 500 cycles of your wave per second, which means you will have 500 cycles in every 20,000 samples. herbie\u0027s spices sydneyWebThe DFT is in general defined for complex inputs and outputs, and a single-frequency component at linear frequency \(f\) is represented by a complex exponential \(a_m = \exp\{2\pi i\,f m\Delta t\}\), where \(\Delta t\) is the sampling interval..
