The peak of the modulation envelope increases to one plus the modulation index:
Amplitude (t) = Ao * (1 + m) * sin (wt) where Ao is the unmodulated amplitude and m is the modulation index (0.8 in the cited example). -- Ken Javor Phone: (256) 650-5261 From: "Ralph McDiarmid" <[email protected]> List-Post: [email protected] Date: Wed, 15 Aug 2007 13:45:13 -0700 To: <[email protected]> Subject: RE: field strength and modulation I¹ve been informed that a 20V/m field when modulated to depth of 80% produces a 36V/m field strength. Would someone explain how that works. I¹m puzzled.
