of signal distortion and Inter Symbol Interference (ISI)?

a. Photodetector

b. Amplifier

c. Equalizer

d. None of the above​

Answer 1

Answer:

An equalizer is used as frequency shaping filter.

Answer 2

c. Equalizer

• As a frequency shaping filter, an equalizer is employed.
• A photodetector is a circuit element that turns light into electricity. A photodetector converts optical AV signals in a fiber optic receiver.
• An amplifier is a type of electronic device that boosts a signal's voltage, current, or power. Wireless communications and broadcast, as well as audio equipment of all kinds, employ amplifiers. Weak-signal amplifiers and power amplifiers are the two types of amplifiers.
