- The top image displays a regular, periodic pattern of vertical black and white stripes. This represents a signal with a single, dominant spatial frequency.
- The bottom image shows an irregular, non-periodic pattern of vertical lines with varying widths and spacing. This represents a signal composed of many different spatial frequencies.
- The Fourier transform of the top image would show a few sharp peaks at specific frequencies, corresponding to the dominant periodicity.
- The Fourier transform of the bottom image would show a broad, continuous spectrum, indicating the presence of many different frequencies without a single dominant one.
