how to convert analog signal to bit stream

I generate a analog signal cos(2pi*f*t), fs is sampling frequency and I denotes quantization levels. How to convert the analog signal to bit stream

[Walter Roberson]

How do you generate the analog signal?

[Murali Krishna AG]

t=0:1:30;

f=1000;

x=cos(2*pi*f*t)

That is not an analog signal. An analog signal is created by outputing to a hardware device. What you have is a digital signal.

Your description said I denotes quantization levels. If so then

I = linspace(-1,1,32);

t = linspace(0,1,75);

f = 17;
x = cos(2*pi*f*t);
plot(t, x)

binnumber = discretize(x, I) - 1;
binnumber(1:10)

ans = 1×10

30 17 0 9 29 24 4 3 23 29

num_bits = ceil(log2(length(I)))

num_bits = 5

as_char_binary = dec2bin(binnumber, num_bits);
as_char_binary(1:5,:)

ans = 5×5 char array
    '11110'
    '10001'
    '00000'
    '01001'
    '11101'

binary_stream = reshape((as_char_binary - '0').',1,[]);

stairs(binary_stream); ylim([-.1 1.1]); xlim([0 50])
