QUESTION

Butterworth BP filtering in C/C++, strange spectrum

Asked 2018-Jul-31 at 22:35

I got a Bw BP C code from here, https://www-users.cs.york.ac.uk/~fisher/mkfilter, as commented in other OS topics, and made a 250Hz, 4th order, passing from 10 to 20Hz.

Below is the code of this filter, adapted from the code provided at this site, and added the lines to multiply the real and imaginary parts of the input signal (coming from a fw FFT R2C):

The generated C code is the recurrence relation which describes the filter behaviour in the time domain. Each index refers to a sample of the filtered input signal (what you might get from an ADC).

You 'broke' the code by:

Adding a 9th sample, where there should be none.
Somehow splitting the data in real/imaginary components (Q/I ?) which is not what the code is intended for.
