A low-power multichannel electromyographic signal data acquisition system. 1987

P Hortensius, and A Quanbury, and S Onyshko

The development of a stand-alone low-power EMG data acquisition system is described. The resulting design operates at low power (approximately 350 mW) and gives four channels of signal measurement with a maximum sampling rate of 10 kHz. Therefore, the data acquisition system described is ideal for low power data acquisition using a microcomputer. The digitized results are available to the microcomputer in a 12 bit signed magnitude form. This system was designed and implemented for use in a microcomputer-based myoelectric limb controller, however, its use is not limited to this application.

UI	MeSH Term	Description	Entries
D008838	Microcomputers	Small computers using LSI (large-scale integration) microprocessor chips as the CPU (central processing unit) and semiconductor memories for compact, inexpensive storage of program instructions and data. They are smaller and less expensive than minicomputers and are usually built into a dedicated system where they are optimized for a particular application. "Microprocessor" may refer to just the CPU or the entire microcomputer.	Computers, Personal,Microprocessors,Computer, Personal,Microcomputer,Microprocessor,Personal Computer,Personal Computers

D019736	Prostheses and Implants	Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
