DFT 32 Samples.
The applet below allows one to see the DFT and DTFT of 32 samples.
Each sample can be adjusted between +5 and -5. and its numerical
value is shown in white on the right.
The magnitude, phase, real and imaginary part of the DFT is
shown in orange, green, blue and pink.
The gif image below shows how the applet should appear when
