% ADBP Convert a decibel signal into a power signal % % [y] = ADBP (x) converts x into a power signal % function [y] = adbP (x) y = 10.^(x/10);

% ADBM Convert a dbm signal into a power signal (Watts) % % [y] = ADBM (x) converts x into a power signal % function [y] = adbm (x) y = 10.^((x-30)/10);

% DBP Convert a power signal into decibels % % [y] = DBP (x) converts x into decibels % function [y] = dbP (x) y = 10.*log10(abs(x));

% DBM Convert a power signal (Watts) into dbm % % [y] = DBM (x) converts x into dbm % function [y] = dbm (x) y = 10.*log10(abs(x/1E-3));
