bunquantize.m

code of an ADC implementation woith matlab simulink

function y = bunquantize(q)
% Calculate the value corresponding to a bidirectionally quantized quantity.
% q is a 2n by m matrix containing the powers of 2 and their signs for each
% quantized value.
% See also bquantize.m.

n = size(q,1)/2;
y = zeros(n,1);
signs = 2:2:2*n;
powers = signs - 1;
for i = 1:size(q,2);
    y = y + 2.^q(powers,i).*q(signs,i);
