    Hi,

    u can call me dumb :), but i cant solve a simple book problem

    - whats the voltage output for a low pass rc filter at the following dB(decibels) with 8v rms input voltage:

    -1 db, -3db, -6db, -20db

    i know whats the voltage at -3db because is 70.7% of the input voltage but cant figure out the rest .

    any help how to solve this please??
