Frequency Modulation (FM) is the encoding of information in a carrier wave by changing the instantaneous frequency of the wave . FM technology is widely used in the fields of computing, telecommunications, and signal processing.
Read moreWhy is amplitude modulation used?
Amplitude modulation is a process by which the wave signal is transmitted by modulating the amplitude of the signal. It is often called AM and is commonly used in transmitting a piece of information through a radio carrier wave . Amplitude modulation is mostly used in the form of electronic communication.
Read moreWhy AM is used in broadcasting?
AM is used for broadcasting because its use avoids receiver complexity . Only a diode and a capacitor are sufficient to separate the audio signal from the AM wave.
Read moreWhy AM is used?
Quadrature amplitude modulation: AM is widely used for the transmission of data in everything from short range wireless links such as Wi-Fi to cellular telecommunications and much more . Effectively it is formed by having two carriers 90° out of phase.
Read moreWhy modulation techniques are used?
Modulation is the process of converting data into electrical signals optimized for transmission . Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method.
Read moreWhy is digital modulation better?
Digital Modulation (DM) gives more capacity of data, high information security, and accessibility of a faster system by enormous quality communication . Therefore, DM techniques have a huge demand due to their capacity for communicating superior amounts of information than AM (analog modulation) techniques.
Read moreWhat type of modulation is OFDM?
Orthogonal Frequency Division Multiplexing (OFDM) is a digital multi-carrier modulation scheme that extends the concept of single subcarrier modulation by using multiple subcarriers within the same single channel.
