Answer / billy dean ward

If you are talking about power, a 3db gain cuts the signal
in half and another 3db gain, for a total of 6 cuts the
signal in half again for a total attenuation of 75%.

Answer / sigma 6

The question is attenuation, thus this represent a decrease
and not addition as a gain is supposed to impose.

The answer in No1 is out of context.

The correct answer would be; 6db of attenuation.

Answer / gulzar ahmed khan lodhi

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.
