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 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 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 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.
