We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

Gathering information on physical phenomena such as force, pressure, light, temperature, strain and current is an invaluable tool when designing many systems. Sensors convert changes in physical ...

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 ...
