Expert Answer
Dear student
Unclear sound of the speaker through the telephone could be due to various reasons:
a. loss of energy during transmission
b. distortions introduced due to mixing of incoming signals
c. distortions while extracting sound waves from the carier waves.
We hope that clarifies your doubt.
