Embodiment Construction
[0021] With reference to accompanying drawing, further illustrate the present invention:
[0022] Such as figure 1 As shown, module A of the present invention includes four multipliers, two adders and one delayer. Every time a pulse clock comes, the value in the delayer is used as the signal f k+1 Enter the module of the next level; the signal f from the previous level k and the signal b from the next stage k+1 Respectively with the parameter -sinφ k and cosφ k The multiplication is input to the first adder A1, and the obtained value is stored in the delayer to prepare for the calculation at the next moment; at the same time, the signal f from the previous stage is k and the signal coming from the latter stage b k+1 Respectively with the parameter cosφ k and sinφ k Multiplied and input to the second adder A2, the formed signal b k Prepare for previous level modules.
[0023] Such as figure 2 As shown, the module B of the present invention includes four multipliers,...
