Wow, did this turn into a contest? I was doing that in the early 60¡¯s. That¡¯s enough from my book. All yours -

Well, in the early 70¡¯s, to be able to do this at home, was fun and rewarding. From some heavy math to a final product. ¨C Mike

Hi

yes a lot of filter work can be verified using peak hold can be time consuming on a adjusting complicated filter

In my early days of designing filters, I used to use a broadband noise generator with a 141T spectrum analyzer. Worked great in max hold after a few sweeps. Just had to make sure the total in-band energy did not overload the front end. Was even able to adjust the zeroes pretty accurately. Since I only built Elliptics, I knew were the poles and zeroes were. 73 ¨C Mike
