WebFeb 24, 2012 · Its generally used to fast-forward or delay a signal, as is necessary in most practical circumstances. Time shifting is mathematically expressed as, Where, X(t) is the original signal, and t 0 represents the shift in time. For a signal X(t) if the position shift t 0 > 0. Then the signal is said to be right shifted or delayed.
