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
Read moreWhich modulation is spectrally more efficient?
Explanation: MSK is spectrally more efficient than the other modulation schemes.
Read moreWhat is BPSK modulation technique?
Binary Phase-shift keying (BPSK) is a digital modulation scheme that conveys data by changing, or modulating, two different phase s of a reference signal (the carrier wave ) . The constellation points chosen are usually positioned with uniform angular spacing around a circle.
Read moreWhat is MSK in digital communication?
The minimum-shift keying (MSK) scheme is used in GSM, a pioneer and a widely-used digital cellular mobile system. MSK can be viewed as either a special case of binary continuous-phase frequency-shift keying (CPFSK) or a special case of OQPSK.
Read moreIs BPSK or bask better?
However, BPSK is as well as showing better Bit Error Rate (BER) compared to BASK . In addition, an analysis was realized about BER achievable in an ASK self-heterodyne optical millimeter-wave system. In this work, it was shown that the need for a depressed decision threshold to optimally detect the received signal [6].
