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 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.

Why dft is used in asic?

Discrete Fourier Transform (DFT) is often used in ASIC (Application-Specific Integrated Circuit) designs for signal processing tasks like filtering and frequency analysis. DFT can efficiently convert signals between time and frequency domains, enabling ASICs to perform tasks such as audio processing, image processing, and communication. It allows ASICs to process data quickly and accurately for various applications.
