Four-level PCM/FM is investigated for reduced spectrum occupancy relative to binary PCM/FM. The spectrum occupancy can be reduced to 65% of binary PCM/FM at a carrier power cost of 4dB, to 58% at a carrier power cost of 7.6dB and to 50% at a carrier power cost of 10.2dB. This performance was achieved using a range type telemetry receiver. Spectra, waveforms, circuit details and BER characteristics are given.Sponsors
