Re: Accuracy of FFT/iFFT on the C55x? ... I'm trying to implement a frequency-domain filter on the TI C55x and ... input and the coefficients, multiply them, and applies iFFT to get the ... I've check the FFT and complex multiplication routines and they seemed ... To simulate linear convolution, you need to pad with enough zeros to keep the snake's tail out of its mouth, then discard the wrapped beginning and end of the result. ... (comp.dsp)
Re: finding frequencies and their amplitude ... Turns out MATLAB defines their fft and ifft differently and actually using ... This will allow you to properly display the spectrum as I ...frequencies with the amplitude being split in half. ... (comp.dsp)
Re: FFT and IFFT ... and I want to interpolate them trigonometrically. ... Do I use FFT... what matlab calls ifft seems to be what my book calls ... something wrong and my example only worked by coincidence.... (comp.soft-sys.matlab)
