Signal to Noise Ratio Calculator

A SNR of 2.5 dB means there might be reduction in data speed.

In digital communication SNR of 16.48 dB means the data speed is clearly readable.

Communication engineer always try to design their system to get maximum SNR.

  • Ar = 20 *Log 10 ( Ao, Output / Ai Input)
    • SNR ( in dB) = Answer

    Simply change the value of output and input for new calculation

    Ar, in dB, Given = 20 *Log 10 ( Ao/ Ai Input )
    Signal output, Ao =

    Simply change the value of output and input for new calculation
