From the formula you gave it is the same. It's just that instead of merely adding, an average is made. However it's like dividing by 3 and then adding. It's still a sum at the end.Godzil wrote: No it's not the same, channel A is outputing a 440Hz square wave for exemple, and B & C are forced at 1V, you will have a 1V (full scale) square wave. If B and C are forced at 0V (which is more likely IRL) it will oscillate between 0 and 0.3333V
It's the same things as connecting AA battery in parallel, the voltage is not adding, you are not going to have 4.5V by doind that, but only 1.5V (or less if they don't have the same voltage)
So your three 1.5V AA batteries can be looked like three 0.5V ones, with added voltage. If not, i'm more and more confused
I don't have the required knowledge to do that (more or less noob at electronics).Godzil wrote: For the LM386, to know at which level it is going to saturate, just look at the schematics and calculate the amplifier gain (too late for me here to do that)
