seq.m

不适用matlab自带滤波器函数的fir低通滤波器设计

function[nrzseq]=seq(sequence)

n=numel(sequence);

N=2^n-1;

register=[(zeros(1,n))+1];

nrzseq(1)=register(n);

for i=2:N
    
newregister(1)=mod(sum(sequence.*register),2);

for j=2:n
    
newregister(j)=register(j-1);

end;

register=newregister;

nrzseq(i)=register(n);

end
