C++ (Cpp) filterS Examples

Example #1

File: OSM_stream.cpp Project: abcweizhuo/Test3

void OSM_cSizeDist::setRR( double s1, double s2, double p1, double p2 )
{
    filterS( s1 );
    filterS( s2 );
    filterP( p1 );
    filterP( p2 );

    s0 = s1;
    x0 = log(s1);
    dx = log(s2) - x0;

    p0 = p1;
    y0 = log( -log(p1/100) );
    dy = log( -log(p2/100) ) - y0;
}

Example #2

File: OSM_stream.cpp Project: abcweizhuo/Test3

double OSM_cSizeDist::percentRR( double size )
{
    double x, y, retVal = 0;

    if( dx==0 )
    {
        retVal = p0;
    }
    else
    {
        filterS( size );
        x = log( size );
        y = y0 + dy * (x-x0)/dx;
        retVal = 100 * exp( -exp(y) );
    }
    return retVal;
}

Example #3

File: fskmodem_float.c Project: bugrahantopall/asterisk

static inline int demodulator(fsk_data *fskd, float *retval, float x)
{
	float xS,xM;

	fskd->cola_in[fskd->pcola] = x;
	
	xS = filterS(fskd,x);
	xM = filterM(fskd,x);

	fskd->cola_filter[fskd->pcola] = xM-xS;

	x = filterL(fskd,xM*xM - xS*xS);
	
	fskd->cola_demod[fskd->pcola++] = x;
	fskd->pcola &=  (NCOLA-1);

	*retval = x;
	return 0;
