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 ...

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

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 ...

While fewer and fewer people are listening to FM radio today, it was hot stuff amid its widespread rollout during the late ...

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 ...

Pulse compression is an important technology in modern radar system, which promotes the developments of modern radar technologies towards higher speed and ranging accuracy. The FMCW signals, with the ...

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 ...

The products are available in two industry-standard form factors: PCIe cards for direct installation in PC-based systems, and LXI stand-alone instruments that support Ethernet-based control in ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
