Question

1. identify a major disadvantage (con) of using analog signals, especially when copying or sending them repeatedly.

Explanation:

Analog signals are continuous. When copied or sent repeatedly, noise (unwanted signals) gets added, degrading signal quality (attenuation and distortion increase with each replication/transmission). This is a major disadvantage compared to digital signals (which can be reconstructed accurately).

Answer:

A major disadvantage of using analog signals when copying or sending them repeatedly is that they are prone to signal degradation (noise accumulation and distortion) with each replication or transmission, as analog signals are continuous and any noise introduced during the process gets added to the original signal, leading to a loss of quality over time.
