👉 Nonspectrality is a concept in statistics and signal processing that refers to the lack of spectral information contained within a signal. This can occur when there are no frequencies present in the spectrum, or if the spectrum contains only one frequency with no other frequencies present. Nonspectrality can be caused by various factors such as noise, aliasing, or the presence of low-frequency components that do not contribute to the overall spectrum. In signal processing, nonspectrality is often used to
