Dear All LTspice users:









Below you will find a link to a video that I created on the subject of
IMD, LTspice is used in part 1 (Part 2 confirms the theory of part 1 using
some lab experiments, is has not been released)



to perform simulations that confirm classroom theory.







Part 2 will have lab experiments using a spectrum analyzer, and the same
circuits that were used in part 1.





I expect to release part 2 next week.

















enjoy.





Sincerely,





Julio Rodriguez

My engineering information defines the order of IMD as "The order of a given intermodulation product is the sum of the absolute values of the coefficients". Thus what you have labeled as "First Order Products" is called "2nd order" and what you have labeled as "Second Order Products" is called "3rd order".

Regards, (9V1MI, WN8P) Larry

Dear Lawrence:





Thanks for your feedback, I have always been under the impression that
first order products were "simple sum or difference"



I will research this further, and make changes as necessary.



Again, thank you very much for feedback.



Sincerely,





Julio Rodriguez

Yes, according to the International Electrotechnical Vocabulary:

702-07-67

intermodulation product order

a sum p + q + ... of the absolute values of integral coefficients p, q, ... of the formula: f = p*f1 + q*f2 + ... giving the combination frequency of an intermodulation product in terms of frequencies f1, f2 ... of the spectral components at the input of a non-linear device or transmission medium

The last ten words are not sensible, but the rest is.

Dear John:



Thank you very much for your feedback, I will be revising the video this
morning



to make the necessary corrections.







Sincerely,





Julio Rodriguez
