Working Principles

AD9837BCPZ-RL7 utilizes a DDS (Direct Digital Synthesis) technique to generate waveforms. It consists of a phase accumulator, a sine lookup table, and a DAC. The phase accumulator generates a digital value that represents the desired frequency, which is then used to index the sine lookup table. The output of the lookup table is converted into an analog signal by the DAC, resulting in the desired waveform.
