Here I have used the equation x(t)=230 Cos (100πt+π/4) at frequency 50Hz which is sampled at a sampling frequency of 600Hz i.e. 12 samples per cycle. in this I have to calculate Samples, recursive and non recursive phasor updates. I have built 1 model for nonrecursive. I am getting the correct samples. but, In non-recursive X^N-1= root 2/N* SIGMA n=0 TO N-1. x(n)* e(-j*n*theta), as showm in attached pic. I have also attached the model and the referenced paper. Instead of using simple complex numver as circled with black. i have to used loop from n=o to n=N-1. Where N=12. So, please tell me . So that I can get nonrecursive updates solution with polar plot.
