Because [[Discrete Time_Old Kiwi|DT]] signals repeat, a simple convolution can produce inaccurate results.  Therefore, something must be done to correct.  The most common operation is to pad the two signals with zeros so that the length of each signal is the length of the longer plus the length of the shorter.
