Hi @pops,
don’t you mean the signal is inverting since your example cites one as non-inverting and two as interting? What am I missing?
No, that example is non-inverting.
All we're doing is adding the number of gain stages in the signal path. A non-inverting component has an even number of gain stages and an inverting component has an odd number of gain stages.
Think of it this way:
- For a non-inverting component, assign 2 (or any even number).
- For an inverting component, assign 1 (or any odd number).
So: non-inverting + inverting + inverting:
2+1+1 = 4.
Even number of gain stages = non-inverting.
