filter realization help

[maduba12001]

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:

[SIZE=13.3333px]y[n]=0;[/SIZE]

[SIZE=13.3333px]for(i=0; i<n; i++)[/SIZE]

[SIZE=13.3333px]y[n] += x * b;[/SIZE]





[SIZE=13.3333px]see:[/SIZE]

[SIZE=13.3333px]What language is that? Never seen (long long) before. Perhaps like a double in C ?[/SIZE]

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