1. A system of implementing precision time delays, comprising:

  • a clock input, said clock input being split into at least two separate clock inputs with a specified phase shift therebetween;

    a delay count providing input to a first lookup table, said first lookup table providing a first output to a first digital to analog converter, the output of said first digital to analog converter being multiplied with at least one of said at least two separate clock inputs thereby providing a first multiplied signal, said first lookup table also providing a second output to a second digital to analog converter, the output of said second digital to analog converter being multiplied with a second of said at least two separate clock inputs to provide a second multiplied signal;

    an addition and output means to add said first multiplied signal to said second multiplied signal;

    a variable threshold, said variable threshold receiving as one input the output of said addition and output means; and

    a second lookup table, said second lookup table'"'"'s output providing a second input to said variable threshold, thereby enabling a desired delayed output signal from said variable threshold.
