Answer 1

quadrature amplitude modulation is a modulation technique that combines two different amplitudecombinations with eight different phase combinations modulation to send four bits persymbol.

Answer 2

The answer is A. Quadrature amplitude modulation

Step-by-step explanation:

Quadrature amplitude modulation or QAM is a type of digital modulation used in telecommunications.

QAM is a technique that involves the combination of two amplitude-modulated (AM) signals within a single communication channel through the use of analog modulation or amplitude modulation techniques to optimize communication.

QAM results in more efficient bandwidth for better communication.
