Answer Posted / rohithmc
i agree with your answers. let me take voltage as 0.6 instead of .5. now power is directly proportional to the square of voltage. i.e p=.7745. in db (20 log.7745) which is
2.2 db down point. i feel like its more appropriated than 3 db. For increase in little voltage, db is reduced. so that we can get better cut off.
