write amatlab script function to carry out a DFT. the funtion should work for any number of input points i,e. the number of points in the transform is not to be hard coded. Generate a 1024 point signal sampled at 1kHz made up adding four sine wave. use your funtion to find the frequency domain representation of this signalk. compare the time your funtion needs to carry out a 1024 point DFT with the time needed by the FFt FUNTION ON MATLAB. repeat the time comparison for an 8192 point signa. (same freq. amp-t).
