A fast Fourier transform (FFT) is a calculation that figures the discrete Fourier transform (DFT) of a grouping, or its backwards (IDFT). Fourier examination changes over a sign from its unique space (frequently time or space) to a portrayal in the frequency area as well as the other way around. In this Paper we have done VLSI implementation of the decimation in frequency-Fast Fourier Transform algorithm. Previous it is designed using the vedic multiplier. The proposed DIF-FFT is design using the booth multiplier. The Xilinx platform is used to simulate and implementation of the work and to calculate and improve various parameters values like area, power, delay and power delay product (PDP) is prime objective of this research work.
