The difference between -+3b frequency and 6db frequency.
I have a Fet amplifier that I'm required to get its -3db and +3db frequencies, easy.
but it is also required that I find the 6db frequency, what is that?
Voltage dB is 20*log(V2/V1). Plugging into the equation gives -3dB being where the voltage drops to 0.708 of it's initial value and +3dB is where it increases to 1.413 of its initial value. ±6dB is where the voltage is 2.0 and 0.5 of the initial value.
