ABSTRACT:
A digital apparatus for performing minimum-shift-keying (MSK) modulation includes an oscillatory circuit which provides two frequencies related in a predetermined manner, and also includes a processing circuit which divides a stream of digital data to be transmitted into two parallel substreams, one substream comprising even numbered bits from the serial stream and the other substream comprising odd numbered bits from the serial stream. A combining circuit selects one of the frequencies provided by the oscillatory circuit according to the equivalence or divergence of the states of the digital substreams, and further provides as an output the selected frequency waveform or its inverse according to the state of one of the substreams.
