Abstract
A method for transmitting information with a desired bandwidth while suppressing interference due to harmonics of a system-wide signal, by transmitting each bit of information as a pair of spaced rectangular envelope modulation pulses having a time interval therebetween essentially equal to the reciprocal of the difference between the frequencies of a carrier and of adjacent harmonics of the undesired system-wide signal. A sequential plurality of double-pulse modulating waveforms can be transmitted for reception by a receiving means having a like plurality of demodulators each synchronized and sequentially enabled only when one of the pair of modulating pulses are present. A novel double-pulse demodulator means, capable of essentially rejecting undesirable harmonics in a system utilizing a data carrier modulated to be interlaced between sequential harmonics of a system-wide signal, and novel means for synchronous gating thereof, are disclosed.
