hello everyone,

I was trying to understand the closed loop gain which is given by Vout(s)/Vin()s when implementing the gain loop meter, it says it measures the closed loop gain. my question is it the Vout(s)/Vin(s)? because when used I see an input from the Vout and the perturbation is outputted from the gain loop meter to the +/- block ,could it be the bode plot given by the gain loop metr is just the Vout/Verr as shown in this figure

best regards,
