Data Acquisition Basics – What is an A/D Converter?

Analog : Data represented by continuously variable physical quantities, i.e. moving clock hands. Digital: Data composed of bytes of information sampled at regular intervals. Data acquisition for life science research and education has come a long way since the heyday...
Origins of Electrophysiology

Origins of Electrophysiology

Physiology and electricity share a common historical journey. In the mid 1700’s, the Austrian writer/philosopher J. Sulzer noted that when two metal discs were placed on his tongue—one copper and one zinc—the combined metals yielded an odd sensation and taste. He...
