Sliding average filtering algorithm (recursive averaging filter method)

Adnum for the number of ad received

The number of elements of the GN array value_buf[]. This function is called primarily, using the array of parameters to pass the value

const int GN = 12;

int filterptr = 0;

bool IsFirst = true;

public float gsum = 0;

float[] Gbuf = new FLOAT[GN];

Float Glidefilterad (float adnum)

{

if (IsFirst)

{

IsFirst = false;

for (int i = 0; i< GN; i++)

Gbuf[i] = Adnum;

Gsum = Adnum * GN;

return adnum;

}

Else

{

Gsum-= gbuf[filterptr] + adnum;

gbuf[filterptr++] = Adnum;

if (filterptr = = GN)

filterptr = 0; FIFO first, then average

return (GSUM/GN);

}

}
