I am hoping someone can give me some assistance on a circuit I am working on, I've tried many, many configurations and cant seem to get a functional circuit that performs all functions.

Circuit characteristics:

Input: 0-5v @ DC-5khz
Output: 0-5v @ DC-5khz

Functions:

High limit:
limit Max out V
For any given input voltage, scale output to match high limit, ie, no clipping

Yields

Low Limit:
limit Min out V
For any given input voltage, scale output to match low limit, again, no clipping

Yields

Offset:
Change offset voltage
change the center point of the output

Yields

OR

Gain:
Change total gain-Optional can be controlled through other functions
change both high and low limit above/below center point

Yields

OR

I have managed to get each individual function through gain control and voltage adding with Op-Amps, but combining them into a single circuit with 1 input -> 1 output has proven difficult.

Thanks in advance.

You need to design a function generator using amps and doides as linear gates.
