Can I use a DDS to produce modulation waveforms?

I understand that a DDS generates a sine wave. It seems logical that modulating the sine wave should follow easily.

  • Hi Kenny,

              Iam new to DDS Design.Iam making DDS based synthesizer for 88-108MHz band.I can able to get this full spectrum with 30.720MHz reference.But iam confused with Modulation frequency.Our requirement for modulation freq is: 70kHz.Pls suggest me how to use AD9954 DDS IC for this requirement.Pls guide me to meet this requirement.If possible ,pls share ckt diagram for this with me.Pls help me...

    Regards,

    Prasad.
