DTFT and Convolution using FFTW library and C++ programming
This project shows how we can perform the discrete time fourier transform and convolution using FFTW library and C++ programming language. By sampling the signal given we have converted the input signal in the time domain to the discrete.We have performed the discrete time fourier transform by using the inbuild libraray functions. The outputs obtained by the convolution using FFTW are compared with the outputs obtained from the pure C++ programming to check the validity and accuracy. The compared data is stored to text files and graphs are plotted to compare.
