RF::Functions - Perl Exporter for Radio Frequency (RF) Functions
use RF::Functions qw{db_ratio ratio_db}; my $db = db_ratio(2); #~3dB
RF::Functions is a lib for common RF function. I plan to add additional functions as I need them.
Returns dB given a numerical power ratio.
my $db = db_ratio(2); #+3dB my $db = db_ratio(1/2); #-3dB
Returns power ratio given dB.
my $power_ratio = ratio_db(3); #2
Return power loss in dB given frequency and distance in the specified units of measure
my $free_space_loss = fsl_mhz_km($mhz, $km); #returns dB
"log10" in POSIX, "nearest" in Math::Round
