Frequency modulation (FM) synthesis is often viewed as complex, but it's a powerful tool for creating twisted bass sounds. Think of regular vibrato, where an LFO - the modulator - modulates the pitch ...

Aeva and Blackmore modulate the frequency of the laser wave instead of the amplitude. The lasers don't pulse, as AM lidar does. Instead, small frequency changes are made to a continuous wave.

Frequency modulation has been around for over 80 years thanks to inventor and EE Edwin Armstrong. FM is a popular modulation scheme used to transmit information on a high-frequency radio carrier ...

This article attempts to provide an understanding of the electromagnetic spectrum with a focus on radio frequency (RF), optical fibers, various modulation techniques, propagation characteristics ...

In Frequency Shift Keying the transmitted signal shifts between two different frequencies to represent binary data, like two different notes from a piano. This would technically be 2-FSK modulation.

The circuit uses two integrated circuits from Maxim. IC1 a MAX4467, is an amplifier raising the microphone signal to a level suitable for frequency modulation (FM). IC2 is a voltage-controlled ...

The relative amplitudes of the carrier and the first 10 side frequency components of a frequency modulated signal for different values of modulation index. It can be gathered that for small levels of ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors ...
