Title: Comparing RMS and ENVELOPE detectors for modding AM receivers Post by: IN3IEX on November 04, 2011, 07:33:05 AM The recent availability of low cost True RMS demodulators for AM signals has prompted AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
the quest for more knowledge about the performances of RMS AM demodulators compared to ENVELOPE AM demodulators. Both are non-linear circuits, therefore the answer may come from SPICE simulations..... Full story here: http://www.ing.unitn.it/~fontana/AmDetCompare.pdf An example of RMS AM demodulator for the Drake R4B here: http://amfone.net/Amforum/index.php?topic=29362.0 It really needs it. 73 Giorgio |
