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 ...

When engineers hear the phrase LiDAR, an acronym for Light Detection and Ranging, they generally think of time-of-flight (ToF ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

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 ...

Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But ...

Edwin Howard Armstrong, bald, blue-eyed, well-heeled professor of electrical engineering at Columbia University, has made a tidy fortune for himself by inventing the super-regenerative and ...

Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...
