Hi Guys,

Does anyone know if it's possible to create a circuit for an AC analysis that will invert another signal? I've tried all sorts of things (e.g. using behavioral elements), and looked on online, but have not been able to find a solution. The BV element can invert and multiply signals for time domain analysis (.tran) but in the frequency domain it appears to be limited. I've included my circuit below (one of the things I tried) and the results from running it with an AC analysis. The inverted signal should have a value of -6dB but instead is not plotting a magnitude (scale is at 3.08KdB). The reason I'm interested in this is because I'd like to be able manipulate large laplace expressions with the behavioral elements by multiplying and dividing signals representing different laplace expressions.

Thanks for any help you can offer in advance.
