how i can do a recursive discrete fourier transform(DFT) for a decaying sinusoidal signal in simulink to achieve the next algorithm :
Several discrete frequency steps are used by increasing the
time window from 32 samples per cycle to 38 samples per
cycle. That is, the measurement window is increased in
integral steps of 32, 33, 34, 35, 36, 37 to 38 samples as the
frequency is decreasing from 60 Hz to 50 Hz. A total of
seven recursive DFT calculations are implemented (one for
each of the sample window lengths) in parallel and the
appropriate phasors are selected based on the measured
i want know how can i do that .
