I saw this bit, - "These errors are due in part to the perpetuation in print of incorrect formulas for the design of the RIAA equalization networks commonly employed." However, I don't understand why it was an issue in the first place. I'm not an engineer, but I just assumed there was a standard that everyone followed.
What Stanley is stating is that the design equations used by the designers/engineers are not correct. It is one thing to calculate a single pole complex math problem, but when multiple poles are needed, very complex math is needed. The designers/engineers did not understand how to perform the correct math.
I surmised that there are equations in general, standard reference, use that are incorrect and were simply copied by many designers/engineers.
Hope this helps. Cheers.
