Hi all, I am trying to convert a sinewave into binary data by using the Sine wave, Quantizer, limiter, convert blocks. but i am unable to visualise the 8 bits in output.(getting only 1 or 0 in display). Kindly help me in this regard. I want to get all samples data in binary format and then replacing or randomly changing into 0's to 1's.
Thanks in advance.

Did you try converting to a uint8 data type? You will have to fix the scaling as it will be 0 to 255.

i placed SW,qunatizer,limiter, integer to bit conversion block and display block. Should i write any function code (dec2bin) or its enough to use integer to bit converter block?

Hello,
Sorry for the delayed response. What about an "Embedded MATLAB function" block calling this kind of code (1 input, 8 outputs) ?
function [b7,b6,b5,b4,b3,b2,b1,b0] = bitgetuint8(Signal)
B = boolean(bitget(uint8(Signal),8:-1:1,'uint8'));
b0 = B(1);
b1 = B(2);
b2 = B(3);
b3 = B(4);
b4 = B(5);
b5 = B(6);
b6 = B(7);
b7 = B(8);
end
