FIELD: electricity.
SUBSTANCE: method to process of a radio-frequency (RF) accepted signal comprises the following stages: application of programmable amplification to a received RF-signal; generation of a signal related to assessment of energy of a received RF-signal; control of programmable amplification on the basis of an energy assessment signal; transformation of a received RF-signal with lower frequency; detection of system time information in a signal transformed with frequency reduction; tuning of a DC component of a signal converted with frequency reduction, with a relatively accurate method; and tuning of a DC-component of a signal transformed with frequency reduction, with a relatively rough method.
EFFECT: invention provides for automatic control of amplification and compensation of DC level in a combined manner in order to guarantee an appropriate level of a signal at an inlet of an analog-to-digital converter, reduction or elimination of a DC level after a mixer.
