Lecture 35 : Computation of Phasor from Discrete Fourier Transform

 

Review Questions

1. Consider, the following signal
 

  (a) Generate samples on this waveform using sampling frequency of  12 samples per cycle.
  (b) Apply full cycle and half cycle algorithms to estimate phasor from generalized DFT approach.
  (c) Repeat (b) using recursive forms.
2. Now consider the following signal.
 
  Repeat (2) and comment on the accuracy of full cycle and half cycle estimation methods.
