The Fast Fourier Transform. (FFT) is one of the most used tools in electrical engineering analysis, but certain aspects of the transform. are not widely understood–even by engineers who think they understand the FFT. Some of the most commonly misunderstood concepts are zero-padding, frequency resolution, and how to choose the right Fourier transform. size.

This article will explore zero-padding the Fourier transform–how to do it correctly and what is actually happening. The exploration will cover of the following topics:
  1. Zero Padding
  2. FFT Frequency Resolution
    1. Waveform. Frequency Resolution
    2. FFT Resolution
  3. Frequency Domain Resolution Concept Exploration
  4. Choosing the Right FFT Size.
