About This Question

Subject: physics
Chapter: communication systems
Topic: channel capacity hard
Difficulty: Hard
Year: 2025

Solution

Correct Answer:

Increases SNR

The Shannon-Hartley theorem defines the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. The formula is: $C = B lo g_{2} (1 + SNR)$ where $C$ is the channel capacity, $B$ is the bandwidth, and $SNR$ is the Signal-to-Noise Ratio ( $S / N$ ). Increasing either the bandwidth or the $SNR$ directly increases the link's theoretical data capacity.

This hard difficulty physics question is from the chapter communication systems, covering the topic of channel capacity hard. It appeared in the 2025 exam.
