I have to quantise a continuous sin wave into a 16 bit signal and obtain the vector of the quantised signals in the binary form? How to get the binary of a decimal number which might be negative. Can anyone provide me with the code snippet for that?

ts=0.01 % sample time
t=0:ts:10; % time vector
y=sin(t); % your signal
pas=(1-(-1))/(2^15-1) % quantization interval
ye=round(y/pas)
s=sign(ye')
s(s<=0)=0
yq=[num2str(s) dec2bin(abs(ye))] % use the first bit to define positive and negative numbers

Sarah, if you have another question, post a new one and make it as clear as possible

dec2bin(typecast(int16(floor(sin(t) * 32767)), 'uint16'), 16) - '0'
