In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Differential ports make possible the recovery of signals mixed with common-mode noise, and the use of such ports gives rise to the need for measuring common mode rejection ratio (CMRR). Circuit blocks ...

Students set up and conduct specific experiments designed to study: 1) fundamental ME instrumentation systems; 2) fundamental experimental techniques, 3) basic physical principles of mechanical ...

This file type includes high-resolution graphics and schematics when applicable. Instrument amplifiers (INAs) are widely used for signal conditioning in data-acquisition systems and telemetry. Their ...

When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Signals are acquired from the subject by electrodes in contact with the skin, or by needles inserted in living tissue. The source impedance (electrodes, needles, etc.) is usually high and variable. It ...
