If i'm given the noise voltage at the output of an amplifier as 30mV but there is no input signal present how do I calculate the Signal to noise ratio?
I know I need to use the equation snr=log20(Vout/Vin)
but due to there being no input im confused
I attempted log20(30mV/0) however this gives a syntax error on my calculator
any help or advice on where I am going wrong would be greatly appreciated
