The paper proposes a radio pulse demodulation method which allows to extract the signal envelope by taking coherent samples with a frequency not exceeding the carri-er frequency of the received signal. The paper demonstrates the possibility of creation of inertia-free demodulators based on the proposed method, whose principle of op-eration is reduced to performing basic operations in the time domain and forming samples, whose position corresponds to the expected amplitude values of the carrier oscillation and depends on its frequency. Calculations of the errors in determining the amplitude of demodulated signal, the factors affecting the errors, and ways to reduce them are shown. The specific results of studies of the capabilities of the proposed method obtained on the model of a base-based digital demodulator are presented.
