CODE-TO-TIME-MODULATED-SIGNAL CONVERTER Russian patent published in 1997 - IPC H03M7/00 H03M7/12 

FIELD: digital-to-analog converters including those having high output power level. SUBSTANCE: converter has n-bit register to receive and store converted code, n-bit counter with clock input bus, and code comparison unit wherein major energy-carrying frequencies of obtained signal spectrum at constant clock frequency are increased due to introduction of m AND gates, m-input OR gate, AND gate, and OR gate. At same clock frequency, converter provides for 16-fold increase in fundamental frequency and at least 80-fold decrease in low-frequency component amplitude. EFFECT: increased spectrum major frequencies of time-modulated signal obtained and reduced amplitude of low-frequency spectrum components thereby improving signal filtering conditions. 2 dwg
