How to Use the Channel Capacity Calculator

  1. Enter the bandwidth of the communication channel in Hertz (Hz).
  2. Enter the signal-to-noise ratio (SNR) of the channel. This is a dimensionless quantity that represents the ratio of the signal power to the noise power.
  3. Click the "Calculate" button to compute the channel capacity.
  4. The result will be displayed in bits per second (bps).

Understanding the Formula

The channel capacity \( C \) is calculated using the formula \( C = B \log_2(1 + \text{SNR}) \), where:

  • \( C \) is the channel capacity in bits per second (bps).
  • \( B \) is the bandwidth of the channel in Hertz (Hz).
  • \( \text{SNR} \) is the signal-to-noise ratio, which is a measure of the level of the desired signal compared to the level of background noise.

This formula shows that the channel capacity increases with both the bandwidth and the signal-to-noise ratio. Higher bandwidth allows for more data to be transmitted, while a higher signal-to-noise ratio means the signal is stronger relative to the noise, allowing for more reliable communication.
