If you are talking about power,
a -3db gain or 3dB attenuation cuts the signal power
in half i.e. signal becomes 50% in power.
3dB attenuation = 50% of original
6 db attenuation = 50% of 50% = 25% of original power
So, 6dB attenuation or -6dB Gain is Actually makes signal 25% of original power.
Or in other words 6dB= 75% attenuation.
