1. [AMPS] 3rd order IMD driver/final (score: 1): Author: amps@txrx.demon.co.uk (Steve Thompson); Date: Thu, 1 Oct 1998 08:20:29 +0100; As G8WRB mentioned earlier, the final result depends on the phase - the IMD can cancel as well as add, so your rule of thumb might well be 'typical' as opposed to my 'worst case'. Things can also var; /archives//html/Amps/1998-10/msg00003.html (7,926 bytes)
