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 ...

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 ...

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 ...
