DIGITAL CONVERSION METHOD AND APPARATUS, AND SIGNAL RECONFIGURATION METHOD Russian patent published in 2013 - IPC H03H17/02 H04L27/26 

FIELD: radio engineering, communication.

SUBSTANCE: method for a digital time-sampled band-pass signal with increase in frequency to the required value includes setting a fixed efficient sampling frequency for digital-to-analogue conversion (DAC), performing complex readjustment of the time-sampled band-pass signal for frequency domain mixing thereof, increasing the sampling frequency N times to obtain a time-sampled signal with a higher sampling frequency, frequency domain representation of which comprises a plurality of signal spectra, filtering to select at least one spectrum, conversion thereof to a continuous signal using DAC, filtering the continuous signal to select the signal spectrum at the required frequency in the frequency domain. The apparatus for digital conversion with increase in frequency of a time-sampled band-pass signal to the required value includes a DAC, a complex tuner, a digital device for increasing sampling frequency N-fold, a signal spectrum filter and a post-DAC filter.

EFFECT: enabling tuning in a wide frequency band.
