This is a Python GUI Application Developed by Anshuman Biswal to Perform Fast Fourier Transform (FFT) on a given Signal Sequence, it is written in Python 3.8 and TKinter. Users can find DFT and IDFT of 4-Point,8-Point signal sequence in Frequency and Time Domain using Radix Algorithm, Also Linear Convolution and Circular Convolution using Radix.
