Abstract

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.
