Noise Analysis help says:
Another measure of noise, the “signal to noise ratio,” takes the signal magnitude into account. This is the ratio of signal power to noise power, according to the following formula:S/N = 20*log(VSig/VTot)
where VTot is the total input-referred noise voltage and VSig represents the expected signal amplitude. VSig is a user-defined value that you enter in the Noise Analysis dialog. The default value is 1V.
1. VSig and VTot are rms voltages, right? The "ratio of signal power to noise power" would be 10*log10(PSig/PTot)
2. The value you enter in this dialog is Vrms? But the value you enter in the signal generator component is Vpeak?
3. So there's no way to analyze the total input noise except to calculate total output noise and subtract gain? It would be nice if there were a way to output that number instead of SNR.
