How to convert decades to decibel (amplitude)s
Convert through a plain ratio: decade → ratio → decibel (amplitude). Logarithmic units cannot be converted by multiplying alone.
Decade: A factor of ten. Bode plots are drawn per decade.
Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
