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