WebA time series plot follows. We see a regularly repeating pattern that seems to repeat about every 30 or so time periods. This may not be surprising. The stimulus was applied for 16 time periods (of 2 seconds) and not applied for another 16 time periods (of 2 seconds). So, we might expect a repeating pattern every 16+16 = 32 time periods.

Web3.2 Symbol Periodicity In a time series T, a symbol s is said to be periodic with a period p if s exists “almost” every p time-stamps. For example, in the time series T ¼ abcabbabcb, the symbol b is periodic with period 4 since b exists every four time-stamps (in positions 1, 5, and 9). Moreover, the symbol a is periodic WebAny time series can be expressed as a combination of cosine and sine waves with differing periods (how long it takes to complete a full cycle) and amplitudes (maximum/minimum value during the cycle). This fact can be utilized to examine the periodic (cyclical) behavior in a time series. Periodogram my name is trey and i have a basketball game
