The STM32 series single-chip microcomputer is used as the controller to control the stepping motor through the L9110S motor drive module, thereby affecting the gap of the cone valve. At the same time, ...
Power-line interference (PLI) is the major disturbing factor in all ground-free biosignal acquisition applications. The PLI currents picked up by the body must flow through the sensing electrodes, ...
In Part 1 of this series, we discussed the Wheatstone bridge topology, excitation and calibration methodologies, and basic signal-conditioning techniques using building blocks such as difference ...
