C programing

The goal is to realize a very simple signal processing software. It shouldn't take more than a few hours.

The program will take an input signal, apply a Butterworth filter, and save the output.

Il will provide :

- the function to calculate the butterworth factors,

- a program to generate noisy test signals

The program will allow the user to :

– specify the name of the file to be read

– specify the name of the file for the output signal

– specify the name of the file where the filter characteristics will be stored

– specify filter's characteristics : cut off frequency, filter order

– view the input with Gnuplot

– apply the filter and store the result

– view the output with Gnuplot

- save graphs in eps format

- continue running the program unless the user choose to quit

- signals will be stored in files in 2 columns : time, value, with the sampling

the program must run with smoothly with Linux. I want the sources, with a makefile. It will use memory allocation, custom data structures, and will be as short as possible. Text-base interface is fine.

This should be a fairly easy gig for an experienced programmer. The only difficulty is the delay : I need it for the 04/08 (8th of april), 17h00 GMT. If you can't do it for this time, please do not bid.

small correction :

- signals will be stored in files in 2 columns : time, value, with the sampling period on first line
