Shannon Capacity Calculator

Compute max data rate C = B·log₂(1 + SNR) from bandwidth and SNR (dB).

Input Data

Input Bandwidth B.
Hz
Input SNR.
dB

Results

9,967,226.26bps
Shannon C = B·log₂(1 + SNR).

At a glance:Shannon Capacity Calculator: enter parameters to compute results; complements related calculators.

Formula

C = B · log₂(1 + SNR_lin); SNR_lin = 10^(SNR_dB/10).

How to Use

  1. Enter bandwidth B, SNR (dB).
  2. It returns max data rate (bps).

Case Studies

B=1 MHz, SNR=30 dB → ≈9.97 Mbps

Linear SNR = 1000.

FAQ

Units?

Result is bps (bits/s); divide by 1e6 for Mbps.
