filter realization help


Recommended Posts

I need a help with filter realization. I dont understand how this works. This is a multiply and accumulate filter, I dont understand why cof[0] constant is multiplied, here is the code cof is the filter coefficients and sample is the samples. Any help with this very appreciated. Thank you

It looks similar to:


for(i=0; i<n; i++)

y[n] += x * b;



What language is that? Never seen this spy apps and (long long) before. Perhaps like a double in C ?

This is the only integer data type in Visual C++. This data type has only been granted rights in recent versions of C++.
