FAQs
1. What is the significance of the signaltonoise ratio (SNR) in channel capacity?
 The SNR represents the quality of the communication channel. Higher SNR values indicate better signal quality and, consequently, higher achievable data rates.
2. How does bandwidth affect channel capacity?
 Bandwidth determines the maximum rate at which information can be transmitted through the channel. A wider bandwidth allows for higher data rates, resulting in increased channel capacity.
3. Can channel capacity be exceeded?
 Channel capacity represents the theoretical limit of reliable data transmission. While it’s possible to approach this limit with advanced coding schemes, surpassing it is not feasible due to the constraints of the communication channel.
