%if
% input sequence
bits = [1,0,1,1,0,0,0,1];
% Mapping
for a=1:length(bits)
  if bits(a) == 1
      bit(a) = 5;
  else
      bit(a) = -5;
  end
end
i = 1;
t = 0:0.01:length(bits);
for b=1:length(t)
  if t(b) <= i
      y(b) = bit(i);
  else 
      y(b) = bit(i);
      i = i+1;
  end
end
plot(t,y);

I am trying to change the length of 1 bit from 1s to 1us which will change step from 0.01 to 1e-8 but it gives me an error and if I just plot it on 0 to 8e-6 without proper implementation it will only print the first value which is between 0 and 1. Any ideas on how to plot an array of length 8 on timescale 0 to 8e-8??
