Testimonials 2023

A testimonial from Michael Hoelzl of IRS Systementwicklung GmbH

By email, 22 October 2023

I would like to personally thank Mr. Armstrong for all the incredibly informative material about EMC he has produced over the last decades. I cannot imagine how many hours he must have spent writing it all down!

German literature on the subject of EMC is terribly academic and of no real use to the working engineer. What a relief it was do discover Mr. Armstrong’s material which immediately helped me get an understanding of the underlying problems!

Thanks to Mr. Armstrong I can now proudly say that I am able to design modules which meet the corresponding EMC standards. It sounds like a ridiculous accomplishment to outsiders, but if you have been in my shoes I am sure you know that it most certainly is not as easy as it sounds!
