function g = er_conv(f1,f2)
% function g = er_conv(f1,f2)
%   Function to convolve given transfer functions in the time domain.  Takes
%   two input structs F1 and F2 with complete transfer function coefficient 
%   vectors and returns result in struct G.

% Unpack input struct
num1 = f1(1).tf_complete;
den1 = f1(2).tf_complete;
num2 = f2(1).tf_complete;
den2 = f2(2).tf_complete;

% Perform convolution in time
num3 = conv(num1,num2);
den3 = conv(den1,den2);

% Repack output struct
f1(1).tf_complete = num3;
f1(2).tf_complete = den3; 
g = f1;
