What you said is kinda confusing so I'm gonna clarify
3dB = √2 which is the amplitude ratio which is equivalent to doubling the power, since power is square proportional to amplitude
6dB = 2, so a 6dB increase in power would be doubling the power, and a 6dB increase in amplitude would be 4x the power
a negative dB is just the reciprocal of the radio, so -6dB is equal to 1/2
- ramshorns 10y ago> 6dB = 2, so a 6dB increase in power would be doubling the power Pretty sure this part isn't right. Decibels are about power ratios, not amplitude ratios. 10 dB is a power ratio of 10, so 20 dB is an amplitude ratio of 10. 6 dB is a power ratio of 10^(6/10) ≈ 3.981 or an amplitude ratio of 10^(3/10) ≈ 1.995.), while 3 dB is a power ratio of 1.995 or an amplitude ratio of 1.413. (It's probably sometimes defined so that 3 dB is a power ratio of exactly 2, making 30 dB 1024 instead of 1000.)
- pitaj 10y agoYes I was wrong about the 6dB. That's a quadrupling of the power, not a doubling. It's twice the amplitude. Unfortunately I can't edit my comment.
