The Distortion Magnifier

Author(s): Cordell Bob

Audio equipment has become so transparent that it taxes the resolving power of all but the most expensive distortion analyzers. Bob Cordell developed the Distortion Magnifier (DM) as an add-on to a distortion analyzer, to increase the resolution. By increasing the distortion fraction in the measurement signal, the DM increases the resolving power of an analyzer by 20 or 40dB. Useable for a stand-alone distortion analyzer as well as with a PC-soundcard and software-based set-up. For availability of a PCB and some specific parts contact
