Fm waves definition
WebFrequency modulation (FM) has numerous advantages over AM such as better fidelity and noise immunity. However, it is much more complex to both modulate and demodulate a carrier wave with FM, and AM predates it by several decades. There are several common types of FM demodulators: WebJan 28, 2024 · AM stands for Amplitude Modulation, and FM stands for Frequency Modulation. Both AM and FM radio programs are transmitted over the air via radio waves, which are part of a range of electromagnetic waves that include gamma rays, x-rays, ultraviolet rays, visible light, infrared, and microwave.
