From some heavy math to a final product. ¨C Mike ? Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 848-245-9115 ? From: [email protected] <[email protected]> On Behalf Of Paul Bicknell ? Hi ? yes a lot of filter work can be verified using peak hold can be time consuming on a adjusting complicated filter ? Regards Paul From: [email protected] [mailto:[email protected]] On Behalf Of Mike Feher ? 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 ? Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 848-245-9115 No virus found in this message. |
