Abstract
A carrier suppressed information signal modulation arrangement employs a plurality of serially coupled modulators. Each of the serially coupled modulators has a carrier input, a modulating signal input and a modulated carrier output. A carrier is applied to the carrier input of the first modulator and the suppressed modulated carrier output of each modulator is coupled to the carrier input of a succeeding modulator. An encoder responsive to the information signal generates modulating signals to be applied to the modulating signal inputs of the serially coupled modulators, such that a product of the modulating signals forms the information signal. The modulating signals applied to each of the serially coupled modulators modifies the modulated carrier output received at the carrier input of the respective modulator to produce a carrier suppressed information signal modulated output of the last of the serially coupled modulators.
