Abstract : The patent describes apparatus for digitally generating information tones and for translating the frequency of transient information tones to a spectrum location amenable to communications. In response to a digital data input, discrete tones of definite assigned frequency and duration are generated and economically combined to form a spurious-free, single-sideband, suppressed carrier signal. The frequency location of the signal is conveniently determined by an ordinary mixing process.
