This is the symbol for the fundamental period of a signal is the minimum duration after which the signal repeats its pattern, defining its most basic cycle. This period is crucial for analyzing the signal's frequency and understanding its repetitive behavior.

This is the symbol for the fundamental period of a signal is the shortest duration after which a periodic signal repeats its pattern exactly. It is a key property that distinguishes the signal's basic repeating unit from its potentially more complex overall structure. Identifying the fundamental period is essential for analyzing and understanding the intrinsic characteristics of periodic signals.
