how to plot binary input using matlab?
x=[1 1 1 0 0 1 0 1 1 0 0 0 ] , frequency is 8Mhz , also i need to plot odd and even samples for two bit interval. kindly help in this regard

plot means many things. You need to clarify what sort of plot you want.
Possibly:
sampleddata = timetable(x(:), 'SampleRate', 8e6, 'VariableNames', {'sample'})
plot(sampleddata.Time, sampleddata.sample)

plot is a a digital waveform for the given data

You're still not giving many details of what you want.
I'd be surprised if there isn't some plotting function for digital signals in the signal processing toolbox or dsp toolbox, but as I've got neither I don't know.
In base matlab, it's fairly easy to get a plot of a digitial signal:
x = [1 1 1 0 0 1 0 1 1 0 0 0 ]; %demo data
sampleddata = timetable(x(:), 'SampleRate', 8e6, 'VariableNames', {'sample'}) %a better way to store the data
stairs(sampleddata.Time, sampleddata.sample);
ylim([-0.5, 1.5]);

try something like this:
n=0;
while n<5000
for i=1:1000
t(i)=now;
x=[1 0 0 1 1 1 0 0 1]; %read your x from sensor
y(i)=sum(x.*2.^(length(x)-1:-1:0));
end
plot(t,y(end:-1:1))
pause(1e-3);
n=n+1;
end

it is taking an infinite loop for execution

important is this part of code:
x=[1 0 0 1 1 1 0 0 1];
y(i)=sum(x.*2.^(length(x)-1:-1:0)); % change the binary digital signal to a dec. number
and
plot(t,y(end:-1:1)); % plotting for an acceptable time interval
It is yours, how you embaded the codes!
