%makeDSVlim(in,T)
%   This function creates a random sequence of a 'in' bits 
%   valued at 0 and 1, which has a DSV to 'T' or less.  This is an
%   NRZ code.

function out = makeDSVlim(in,T)

states = T + 1;
DSV = 1;
chain = [1];
for i = 1:in-1
    if DSV == T
        chain = [chain 0];
        DSV = T - 1;
    else
        if DSV == 0
        chain = [chain 1];
        DSV = 1;
        else
            x = makeNRZ(1);
            chain = [chain x];
            DSV = DSV + (2*x - 1);
        end
    end
