hey,
I have been give a specification for an audio signal but I'm a little confused about it. The specification was that it was 0dBm into 600 ohms.
From what i have read on-line (we are not being taught about the dB scale in the module) this means that there is 1mW through the resistor? Now using p=(V^2)/r i calculate it to be 1.2*10^-3 volts?
Any info on this or the dB scale would be useful (I have searched google and on here but didn't really find anything that helped).
Thanks
