Difference between the DFT and the FFt?
A Discrete Fourier Transform is simply the name given to the Fourier Transform when it is applied to digital (discrete) rather than an analog (continuous) signal. An FFT (Fast Fourier Transform) is a faster version of the DFT that can be applied when the number of samples in the signal is a power of two. An FFT computation takes approximately N * log2(N) operations, whereas a DFT takes approximately N^2 operations, so the FFT is significantly faster simple answer is FFT = Fast DFT
What is full form of DO?

What are the differences between dft and idft?
idft is inverse of dft
What is the unit of the displacement?
dft
What the procedure of dft?
The procedure of DFT can be found by following this website: gov.uk/government/organisations/department-for-transport/about/complaints-procedure.
Why FFT is faster than DFT?
FFT is faster than DFT because no. of complex multiplication in DFT is N^2 while in FFT no. of complex multiplications are N/2(log2N). for example if N=8 no. of complex multiplications required in DFT are 64. while no. of complex multiplications required in FFT are 12 thus reduces computation time.
