Abstract: Un convertidor ascendente/modulador digital de acceso multiple incluye selectores (1606, 1608), que tienen entradas (1602, 1604) y salidas acopladas a primero y segundo filtros de interpolacion (1610, 1626). La salida del primer filtro de interpolacion está acoplada selectivamente a un primer mezclador (1612) y a un primer adicionador (1622), el primer adicionador recibe también un primer valor de fase y la salida está acoplada a un primer acumulador de fase (1616), la salida del cual está acoplada a un primer generador sinusoidal (1614) y acoplada selectivamente a un segundo generador sinusoidal (1630). La salida de cada uno del primero y segundo mezcladores están acoplados selectivamente a un adicionador de salida (1634) y a las entradas del primero y segundo mezcladores. La salida del segundo filtro de interpolacion (1626) está acoplada selectivamente a un segundo mezclador (1628) y a un segundo adicionador (1638) que también recibe un segundo valor de fase y la salida del cual está acoplada a un segundo acumulador de fase (1640) la salida del cual está acoplada selectivamente al segundo generador sinusoidal.

Abstract: A multiple access digital up converter/modulator includes selectors (1606, 1608) having inputs (1602, 1604) and outputs coupled to first and second interpolating filters (1610, 1626). The output of the first interpolating filter is selectively coupled to a first mixer (1612) and a first adder (1622), the first adder also receiving a first phase value, and the output is coupled to a first phase accumulator (1616) the output of which is coupled to a first sinusoid generator (1614) and selectively coupled to a second sinusoid generator (1630). The outputs of each of the first and second mixers are selectively coupled to an output adder (1634) and to inputs of the first and second mixers. The output of the second interpolating filter (1626) is selectively coupled to a second mixer (1628) and a second adder (1638), which also receives a second phase value and the output of which is coupled to a second phase accumulator (1640) the output of which is selectively coupled to the second sinusoid generator.

Abstract: A FREQUENCY SYNTHESIZER (10) HAVING A DIGITAL TO ANALOG CONVERTER (DAC) (40) AND A FEEDBACK SYSTEM WHICH DETECTS THE DEVIATION OF A FREQUENCY MODULATED SIGNAL AND ALIGNS THE DETECTED DEVIATION. DAC (40) PROVIDES A PRESTEERING STIMULUS FOR ALIGNMENT PURPOSES. AFTER PRESTEERING ALIGNMENT, THE GAIN OF DAC (40) IS ACCURATELY SET OF FREQUENCY DEVIATION BECAUSE MODULATION IS SOURCED FROM THE SAME DIGITAL TO ANALOG CONVERTER THAT PERFORMS PRESTEERING.(FIGURE 1)

Abstract: A frequency synthesizer 10 having a digital to analog converter (DAC) 40 and a feedback system which detects the deviation of a frequency modulated signal and aligns the detected deviation. DAC 40 provides a presteering stimulus for alignment purposes. After presteering alignment, the gain of DAC 40 is accurately set for frequency deviation because modulation is sourced from the same digital to analog converter that performs presteering.
