Direct digital synthesizer having selectable and randomized accumulator

专利汇可以提供Direct digital synthesizer having selectable and randomized accumulator专利检索,专利查询,专利分析的服务。并且PURPOSE: To effectively reduce proximity spurious radiation by allowing a 2nd adder to receive an overflow output from a 1st adder and a pseudo random number generated by a pseudo random number generator.
CONSTITUTION: A 2nd full adder 15 adds a pseudo random number from a pseudo random number generator 21 to a 1st full adder 13. The pseudo random number is added to the 1st full adder 13 only when the 1st full adder 13 produces an overflow. The overflow signal is given to an enable fate 17 through a line 14 from the 1st full adder 13 and the enable gate 17 in this state gets through its gate to supply the pseudo random number to the 2nd full adder 15. Thus, proximity spurious radiation is reduced.
