I'm looking through my notes and came across this example. I can't seem to grasp it. The question is: Design a limiter with Av = -10 in the +- 5v output range and Av = -1 outside that range. The attached picture shows the circuit that was drawn with the question. Thus far I have made the following assumptions: - The diodes will always be in opposite bias. One will be an open circuit while the other will be a short circuit. - The op-amp is used to get the Av = -10 gain thus I realize that R2 thru R5 are used to scale down the gain back to -1 when the output voltage falls outside the given range. So how does one go about finding the R2-R5 values and some explanation as to how this circuit operates would be great ! Thanks!
