| double-amplitude-modulation multiplier [¦dǝb·ǝl ¦am·plǝ´tüd ¦mäj·ǝ´lā·shǝn `mǝl·tǝ´plī·ǝr] ELECTRONICS A multiplier in which one variable is amplitude-modulated by a carrier, and the modulated signal is again amplitude-modulated by the other variable; the resulting double-modulated signal is applied to a balanced demodulator to obtain the product of the two variables. |
