The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental ...

Reading quadrature encoder signals at high speeds (e.g., 1MHz, or, 1m/s with a resolution of 1µm) often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...

The AAT001-10E angle sensor emerges as the first commercial sensor to use tunneling magnetoresistance (TMR), which produces a much larger signal than giant magnetoresistance (GMR). Reportedly, TMR is ...
