## Re: Problem with natural logarithmic function in fixed point notation

Hi chalil,I am not facing any problems in computing log(x) or x. The problem is that the float (true) value of x is different from the value of x, computed after...

## Re: Problem with natural logarithmic function in fixed point notation

Hi,I think, we can do the calculations in both the ways.1st Method: ln(0.54 * 16777216) = ln(9059696) = 16.012nd Method: ln(0.54 * 16777216) = ln(0.54) + ln(16777216)  ...

## Re: Problem with natural logarithmic function in fixed point notation

Hi, i didn't understand your logic. Can you explain in detail?

## Re: Problem with natural logarithmic function in fixed point notation

Hi, i have mentioned the similar calculation in the query itself. And moreover, calculating the value of x in fixed point is not my query.

## Problem with natural logarithmic function in fixed point notation

I am facing a problem with natural logarithmic function in fixed-point notation. Let's say x = 0.54, then ln(x) = -0.616186, a negative value => (1)Then in...

## FIR filtering vs linear convolution

I came across a C code for the FIR filter on one of the websites. It is as follows     void fir(short * y, const short *x, const short *h, int n_out, int n_coefs) ...
