Investigation of the properties of signals with phase change according to a triangular law

A systematic theoretical study is presented of the properties of signals with a triangular phase change, providing for high potential noise-immunity and a low level of out-of-band radiation. The energy spectrum of such signals is discretely continuous, making it possible to isolate the reference oscillation and clock pulses by narrow-band filtering of the discrete lines. The reference oscillation in a demodulator of such signals is shown to lack initial phase indeterminacy. The theoretical analysis of the energy spectrum is confirmed by experimental results.
