After “some” RF design courses, he decided that he had learned enough to build his own frequency-modulated continuous wave radar system. From the level of detail on this project, we’d say ...

This chapter includes a discussion of the most widely used forms of pulse compression, those that fall into the general class of frequency modulation. Frequency-modulated (FM) waveforms can entail ...

Frequency modulation is the process of transferring an information signal onto a radio carrier wave by varying the instantaneous frequency of the radio carrier signal. In 1936, the inventor Armstrong ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage ...

The difference is in how the carrier wave is modulated, or altered ... varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current ...

The contactless devices - used for factory automation applications - will incorporate FMCW sensors developed by California-based Aeva, one of only a handful of photonics companies to focus on the ...

Shanghai (Gasgoo)- Bosch announced on December 9 via one of its official WeChat accounts that its cumulative global shipments of millimeter-wave radar have exceeded 100 million units, with over 30 ...

SICK’s new LXRC and LXRH sensors have been designed specifically for continuous level monitoring across many sectors.

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...
