Since to my understanding the X, and Y coordinates typically vary along the second and first dimensions (if generated by meshgrid) or the first and second dimensions (if generated by ndgrid). WebJan 19, 2024 · FFT algorithm overview Simple Sine Wave to Understand FFT. To understand the output of FFT, let’s create a simple sine wave. The following piece of code creates a sine wave with a sampling rate = 100, amplitude = 1 and frequency = 3. Amplitude values are calculated every 1/100th second (sampling rate) and stored into a list called …
