C code for fixed point atan2
Here is a possible fixed point version of the above code. The result is accurate within +/-1 degree. If +/-5 degree errors are acceptable then the r^3 term can be left out with coeff_1b becoming -45. This function returns degrees and not radians. -------------------------------------------------------------------... 25 Feb 2010 11:22

IIR to find minimum, maximum enveloppe of a signal
Hi all, First of all, I'm a newbie in signal processing, so go easy :) I have used an IIR filter to computer the local average of a signal, and it works well. It essentially is what they call in finance a moving average, i.e. the output at a sample point is a fraction of itself and (1-fraction) of its predeces... 26 Feb 2010 17:33
