% MUV = WFDB_adumuv(SIG_NUM, ADU);
%
% Converts signal value(s) in ADU from A/D units to microvolts, based on
% the gain for input signal SIG_NUM.
%
% SIG_NUM: Signal number (note: the first signal is signal number 0, etc.)
% ADU: Signal values in A/D units (scalar or vector)
% MUV: Resulting value(s) in microvolts
