Showing Results For: Direct Digital Synthesis (DDS)
Direct Digital Synthesis (DDS) is a highly efficient technique employed for generating precise and stable analogue waveforms from digital inputs. It operates by digitally controlling the frequency, phase, and amplitude of a waveform, making it an ideal choice for applications requiring rapid and dynamic adjustments. Its compact and power-efficient design also makes DDS an excellent solution for portable and battery-operated devices. They use a phase accumulator, a digital-to-analogue converter (DAC), and a lookup table to convert digital signals into analogue waveforms. The phase accumulator continuously updates the phase value, while the DAC converts this digital information into a corresponding analog signal.
Composed of semiconductor materials, typically silicon, and integrated circuits with DACs, phase accumulators, and oscillators.
