How does direct digital synthesis (DDS) work? There are at least three elements to DDS: a numerically controlled oscillator (NCO) with a phase modulator, a block that converts the phase information to ...

Part 1 describes the basic structures of digital-to-analog convertors. Part 2 looks at interpolating DACs and sigma-delta DACs. A frequency synthesizer generates multiple frequencies from one or more ...

Direct digital synthesis (DDS) and phased locked loop (PLL) capabilities are built into the AD9956 AgileRF synthesizer for low-power applications in marine, military, radar and satellite ...

Direct digital synthesis (DDS) has come a long way since the days when implementations were limited to complex, costly designs that consumed large amounts of power. Today's DDS ICs offer drastically ...
