← Language & CommunicationWhich outcome is most probable when a noisy communication channel's bandwidth is significantly increased, while the signal power remains constant?
A)Increased transmission error rate linearly
B)Reduced maximum achievable data rate
C)Increased channel capacity, approaching limit✓
D)Decreased signal-to-noise ratio at receiver
💡 Explanation
The channel capacity increases with bandwidth according to the Shannon-Hartley theorem because it describes the theoretical maximum data rate. Increasing the bandwidth allows for more signal frequencies, therefore the channel capacity increases, rather than error rate increasing which would happen with increased interference and constant bandwidth.
