The most fundamental digital modulation techniques are based on keying: PSK (phase-shift keying): a finite number of phases are used. FSK (frequency-shift keying): a finite number of frequencies are used. ASK (amplitude-shift keying): a finite number of amplitudes are used.
Read moreWhat is a satellite modulator?
A satellite modem or satmodem is a modem used to establish data transfers using a communications satellite as a relay . A satellite modem’s main function is to transform an input bitstream to a radio signal and vice versa.
Read moreWhy are digital modulation techniques used in satellite communication?
The advantages provided by digital modulation techniques include: Better performance . Better Error detection and correction efficiency. Better Signal to noise ratio so less prone to interference or noise.
Read moreWhat are modulation techniques?
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 moreWhat are the different types of modulation?
Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method . Analog modulation is typically used for AM, FM radio, and short-wave broadcasting.

Read moreWhat is the use of analog modulation?
And analog modulation is the procedure of transmitting low-frequency signals such as TV signals or audio signals with that of high-frequency carrier signals like that of radio frequency signals . In this type of modulation, a bandpass channel is required where it corresponds to the specified range of frequencies.29 Nis 2020
