    Lets cam more about the phase accumulator. How come they performs?

    Brand new consolidation regarding a great D/Good converter and you can an effective DDS onto a single processor can often be also known as an entire DDS service, a home prominent to any or all DDS products regarding ADI.

    Continuous-go out sinusoidal signals features a repetitive angular phase range of 0 to help you 2?. This new digital implementation is not any other. The latest counters bring means lets this new phase accumulator to do something because the a phase wheel on the DDS implementation.

    To understand which earliest function, visualize the fresh new sine-trend oscillation due to the fact an effective vector spinning as much as a level network (look for Figure cuatro). Per appointed point on the brand new phase controls corresponds to very same point on a cycle away from a sine wave. Because the vector rotates inside the wheel, picture that the sine of your perspective stimulates a corresponding output sine-wave. One wave of your own vector around the phase wheel, in the a steady speed, results in you to definitely over course of your productivity sine-wave. The fresh new phase accumulator has the equally separated angular values associated the fresh vectors linear rotation in the phase wheel. The fresh new contents of the new stage accumulator correspond to the brand new situations into the brand new years of your efficiency sine wave.

    The stage accumulator is actually an excellent modulo-Yards counter you to definitely increments its kept number when they get a clock heartbeat. Read More >
