Hi people, first post
Facts:
* I have a project to make a light-board to manage N-channels in 2 different scenes controlled by 2 masters...
* I do not know a thing about electronics, I can not even remember the Ohm thing...
Question:
I've "designed" a circuit (see attachment) to mix two signals in the next way
out = max( master_a . channel_1A, master_b . channel_1B )
mean, get the max value between the product of blah and blah
masters go from 0v to 12v and channel_1A and channel_1B are values from 0 to 1
I found many troubles in the way, and I am pretty sure that the circuit wont work (by the moment)... but I need to resolve the "get the max value" thing
I used two transistors, but there must be something else there... my simulator says that is ok... but I do not believe him.
by the way... transistors are picked randomly (except for the PNP part) from a long list of components
could any one lead me in the right path??
ps: this is GPL, anyone can use this exclusive design for its own
