已经开发了一种技术，可以将肌电信号分解（分离）成其组成的运动单元动作电位序列。它由一个多通道（通过一个电极）肌电信号记录程序、一个数据压缩算法、一个数字滤波算法和一个混合的视觉-计算机分解方案组成。该算法已在PDP 11/34计算机上实现。在该技术的四个主要部分中，分解方案是迄今为止涉及最多的。分解算法使用复杂的模板匹配程序和运动单元的放电统计细节来识别肌电信号中的运动单元动作电位，即使它们与其他运动单元动作电位叠加。一般来说，分解方案的算法不会自动运行。它们需要人工操作员的输入，以在分解过程中保持可靠性和准确性。
A technique has been developed which enables the decomposition (separation) of a myoelectric signal into its constituent motor unit action potential trains. It consists of a multichannel (via one electrode) myoelectric signal recording procedure, a data compression algorithm, a digital filtering algorithm, and a hybrid visual-computer decomposition scheme. The algorithms have been implemented on a PDP 11/34 computer. Of the four major segments of the technique, the decomposition scheme is by far the most involved. The decomposition algorithm uses a-sophisticated template matching routine and details of the firing statistics of the motor units to identify motor unit action potentials in the myoelectric signal, even when they are super-imposed with other motor unit action potentials. In general, the algorithms of the decomposition scheme do not run automatically. They require input from the human operator to maintain reliability and accuracy during a decomposition.
