Filters

In general, there are two different types of filters; Finite Impulse Response (FIR) and Infinite Impulse Response (IIR). The SMA is an example of a FIR filter, whereas the EMA is a IIR filter. The results of the SMA is finite as defined by the lookback period, whereas the EMA applies a recursive calculation, including the previous calculations. Therefore, regardless of how may samples occurred since the impulse event, there is theoretically some contribution in the current output.
