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 ...

Direct Digital Frequency Synthesis (DDFS) techniques have fundamentally reshaped the approach to frequency generation in modern electronic systems. By employing digital methodologies such as phase ...

The USB-DDS project is very useful for amateur radio operators as a reference oscillator sin it generates sine waves from 0 to 40MHz with millihertz resolution under computer control. The universal ...

Specifically designed for wireless, handheld equipment, the AD9913 is the first direct-digital synthesizer to deliver a 250-MHz clock rate while consuming 50 mW of power. The device includes a 10-bit ...
