mitesh Posted July 20, 2004 Report Share Posted July 20, 2004 is there any difference between sinc function and [sin(pi x)]/pi Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted July 23, 2004 Report Share Posted July 23, 2004 Yes. You can not cancel the pi. Quote Link to comment Share on other sites More sharing options...
mitesh Posted July 25, 2004 Author Report Share Posted July 25, 2004 sir,its natural that we can not cancel out pi!My problem is that shhould we treat them as different functions while taking out Nyquist rate for sampling? Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted July 25, 2004 Report Share Posted July 25, 2004 What is interesting is the RMS calculation. The equation is squared before integrating. The sin x is much different from the (sin x) squared. You then simply take the square root. The mean is based on the sinx. So to say that it is the root of the mean squared is not accurate. It's actually the root of the integral of sinxsquared which is not the root of the intergal of sinx quantity squared. Quote Link to comment Share on other sites More sharing options...
mitesh Posted July 27, 2004 Author Report Share Posted July 27, 2004 sir I am not interested in taking a rms value I am just interested in taking out Nyquist rate of sinc x! Quote Link to comment Share on other sites More sharing options...
