Numerous medical and biomechanical applications invol-ve electromyogram (EMG) signal processing in 19 real time. Amplitude analysis of the EMG often requires computation of the signal’s linear envelope. 20 For this purpose, several methods are commonly described in the literature; however, not all match 21 the speed requirement of real-time applications. We introduce an implementation which accelerates 22 the computation of EMG signals linear envelopes, based on the pipe-line commonly found in the literature 23 for this kind of operation. The algorithm improves the computa-tion’s time requirement, at the expense of 24 memory requirement, by using the result of the envelope’s computation at the previous instant. This 25 algorithm saves approximately 96% of the computation time and allows computing linear envelopes of 26 several EMG signals in real time.
