The two types of modulators used in FM communication are mechanical and what other type?

In FM (Frequency Modulation) communication, the two types of modulators primarily used are mechanical and electronic. The mechanical modulator utilizes physical components to create variations in frequency, traditionally found in earlier technologies, whereas the electronic modulator employs electronic circuits to achieve frequency modulation. This method is more prevalent in modern communication of FM signals due to its efficiency and effectiveness in manipulating signals.

Electronic modulators facilitate rapid changes in frequency and can accurately encode information onto a carrier wave, making them suitable for various communication applications. The use of electronic modulators allows for greater control over the frequency deviation, enhances signal integrity, and supports more complex communication systems. This makes electronic modulation the predominant choice for contemporary FM communication systems, leading to advancements in audio broadcasting, television, and other forms of wireless communication.
