Hello,
I have a question that I hope I can ask clear enouph, here goes...
When programming for a low pass digital filter, how do you implement that onto an input signal, say a waveform. Do you take the FFT of the signal after A/D and multiply them together, or do you convolute them in the time domain? What is the proper way?
The reason I am asking is I want to implement a digital filter in a dsPIC using either C or Basic. I am not too familiar with Assembly. How would one code for that, it is confusing me! Can someone please give me a simple example or explanation for an implementation in a language other than Assembly? I understand the theory behind it, just have no experience in implementation.
Thanks for the help!
