Sonali Kangralkar, Rajashri Khanai · International Journal of Computer Applications · 2019
The importance of Digital Signal Processing (DSP) algorithms have increased drastically in recent times, the two important techniques of DSP are the Discrete Fourier Transform(DFT) and the Fast Fourier Transform(FFT).DFT is broadly used in the applications such as convolution, linear filtering etc.Another algorithm to compute DFT efficiently is the Fast Fourier Transform (FFT).Fast Fourier Transform processor has an important role in the field of communication system such as audio broadcasting and digital video etc.This paper deals with the designing of an 8 point FFT using radix-2 DIT FFT algorithm.This 8 point FFT design is implemented using Verilog HDL in Xilinx ISE Software.
