Possibility of Phase-shift keyed signal produced by transient processes on the output of oscillation circuit which are induced by intermittent high-frequency signal phase variations is considered in the paper. Signals generating are realized by two approaches: the first, when magnitude of transient processes impulses is fixed and the second, when width of transient processes impulses is fixed. These approaches provide less requirement bandwidth for signal transmitting comparing with Phase-shift keyed signal produced by standard methods. Spectrograms for these signals are exhibited that were obtained depending on relations of probability zeros and ones in transmitting random binary information sequences. In conclusion: shape of spectrum is depending on relation between probability zeroes and ones in information sequence, changing it from spectrum of harmonic signal to beat-frequency waveform.
