  • Title: Evaluation and design of a small portable EMG amplifier with potential RMS output.
    Author: Shimomura Y, Iwanaga K, Harada H, Katsuura T.
    Journal: Appl Human Sci; 1999 Mar; 18(2):61-7. PubMed ID: 10388160.
    Abstract:
    The present study attempted to design and evaluate a small portable electromyogram (EMG) amplifier that can output enhanced EMG and its root mean square (RMS) value. The production and design were of a laboratory scale without any special or high cost circuit construction. The designed amplifier was actually innovated according to the actual working conditions based on physiological anthropology. The present amplifier was compared with commercially available products and proved to be of practical use. The device was installed with a sufficiently small body depicting 8-channel variable gain AC amplifier and variable time-window RMS-to-DC converter. The prototype was battery-driven and well-shielded to minimize external noise interference.
