GR_conv::vol2db

[Marco Ballini]

I just took a (very) quik look at vol2db in GR_conv.c:

 

float vol2db( float vol)   // must be in range 0.0- 1.0
{
    return(log10(vol));
}

 

But shouldn't it be voldB = 20*log10(vol) ?:

 

float vol2db( float vol)   // must be in range 0.0- 1.0
{
    return(20*log10(vol));
}

And why not use official notation of dB instead of db ?
