if you are studying a (simple) wave described by: x = A sin(kt) then A = amplitude
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.
The amplitude is 1.
That if the original amplitude was A then it is now 2*A.
Amplitude is just themaximum displacementof a wave:
