LoRa is a form of “chirp spread spectrum” modulation. The “chirp” signal sweeps smoothly across specific frequency range: usually 125 kHz, 250 kHz or 500 kHz wide. How long the sweep takes ...

but understanding the electronics behind modulation and demodulation of an FM signal can be confusing. We’ve covered the basics before, but FM is so tightly associated with broadcast radio ...

When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the Universe.

For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's channel) is varied (modulated) by the analog audio signal.

With one signal path for true acoustic tone and another for effects, you'll have maximum control over your live sound ...

preventing signal attenuation and device failure. By integrating strain control and spin-polarized current control, the OSV devices can achieve efficient multi-state modulation, demonstrating at ...

RADAR uses Frequency Modulated Continuous Wave (FMCW), a continuous varying frequency signal modulated at a known rate over a fixed time period. Normal Continuous Wave (CW) signal lacks marker and ...

Rohde & Schwarz upgraded its SMW200A vector signal generator and midrange counterpart, the R&S SMM100A, to significantly enhance error-vector-magnitude performance, ...
