Hi,
In the AWGN block there are two parameters: "Signal to noise ratio" and "Input signal power, referenced to 1 ohm (watts)". I just can’t understand why the parameter "Input signal power, referenced to 1 ohm (watts)" is needed. I think "Signal to noise ratio" tells everything and only the ratio is important.
Thanks Senmeis
