Dual mode amplitude modulation transmit
two signals over an AM carrier.
Patent application no. -
invention relates to amplitude modulation used in electronic
communication devices. Existing method of amplitude modulation employs
change in amplitude of a carrier signal with respect to amplitude of a
modulating signal. In this method amplitude of carrier signal is
modulated on positive and negative side of carrier wave and both sides
carry same modulating signal.
method of modulating two different modulating signals on
one carrier comprises of a device that modulates one modulating signal
on positive side of the carrier wave and another signal on negative side
of a carrier wave before transmission.
