Digital synthesizer - Wikipedia
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds, in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog ...

直接数字合成 （Direct Digital Synthesizer，簡稱DDS）是一种数字电子方式，它从一个单一（或混合）的频率源中产生任意 波形 和 频率。 一个基本的DDS电路包括电子 控制器 、随机访问存储器（RAM）、频率参考源（通常是 晶振）、 计数器 和 数位类比转换器 （DAC）。 要使DDS系统工作需要两个操作阶段：我们称之为编程和运行。 在编程这一阶段里，电子 控制器 把数据载入至 存储器 中。 数据的每一个单元是一个用来表示当前时刻信号幅度的二进制数。 存储器中这些 …
All About Direct Digital Synthesis | Analog Devices
Direct digital synthesis (DDS) is a method of producing an analog waveform—usually a sine wave—by generating a time-varying signal in digital form and then performing a digital-to-analog conversion. Because operations within a DDS device are primarily digital, it can offer fast switching between output frequencies, fine frequency resolution ...
Direct digital synthesis - Wikipedia
Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation , local oscillators in communication systems, function generators , mixers, modulators , [ 1 ] sound synthesizers and as part of ...

Direct Digital Synthesizers - Springer
A major advantage of a direct digital synthesizer (DDS) is that its output frequency, phase and amplitude can be precisely and rapidly manipulated under digital processor control. Other inherent DDS attributes include the ability to tune with extremely fine frequency and phase resolution, and to rapidly `hop' between frequencies.
Direct Digital Synthesizers: Theory, Design and Applications
2000年1月1日 · Traditional designs of high bandwidth frequency synthesizers employ the use of a phase-locked-loop (PLL). A direct digital synthesizer (DDS) provides many significant advantages over the PLL...
A Direct Digital Synthesizer-Based Arbitrary Waveform Generator …
This paper presents an Arbitrary Waveform Generator (AWG) based on a Direct Digital Synthesizer (DDS) with a sub-Hz frequency resolution. The proposed circuit generates a low-frequency arbitrary signal used for amplitude modulation of a microwave (MW) carrier signal, required for qubit entanglement operations with an enhanced gate fidelity in a Trapped-Ion Quantum Computer (TIQC). This is ...
