Truncation error for Fourier transform? 19 45 (1/12/2009 6:59:47 PM) comp.dsp Hi folks, I'm sure I've been told that there are known bounds on the mean square error caused by the truncation of the Fourier transform (analogue, preferably). Anyone know what I'm talking about? I haven't ha... jhealy

Interpretation of sinc interpolation in Fourier domain 4 54 (1/28/2008 1:46:38 PM) comp.dsp Would someone be kind enough to check the argument below. I'm a bi uncomfortable with the conclusion. The equations are in LaTeX format. Some signal, f(t), is bandlimited such that we can represent it wit sam... jhealy

If you were implementing an FFT chip, what would you use? 7 21 (9/6/2005 5:35:04 PM) comp.dsp I'm a PhD student, but new to the business. I'm trying to impliment a fas algorithm on a chip. It's not actually the FFT, but that's a goo guideline to what I'm trying to do. I don't know much about FPGAs and... johnhealy
