________ can be applied to transmissions that carry analog information or digital information and is used to combat intersymbol interference.
A)Forward error correction
B)Diffraction
C)Adaptive equalization
D)Frequency diversity

Question

Quizplus · Accepted Answer

Adaptive equalization is used to combat intersymbol interference by adjusting the frequency response of a receiver in response to changes in the channel. This technique can be applied to transmissions carrying both analog and digital information. Forward error correction (A) is a different technique used to correct errors in digital transmissions. Diffraction (B) is a natural phenomenon where waves bend around obstacles, but it is not a technique used to combat intersymbol interference. Frequency diversity (D) is a technique used to improve signal quality by transmitting the same signal on different frequencies simultaneously, but it does not specifically address intersymbol interference.
