FIELD: radio engineering, communication.
SUBSTANCE: signal modulation method is based on signal multiplication, as a result of which the DC voltage is multiplied with the telegraph signal, and the product is summed with the centered quasi-deterministic signal and the characteristic function of the transformed quasi-deterministic signal is modulated.
EFFECT: narrowing of the frequency band when transmitting discrete information.
