Hi @rena araidy,

To convert 12-bit data to a 16-bit format in MATLAB, we can apply a series of bitwise operations. The process involves shifting the 12-bit values left by 4 bits and right by 8 bits, followed by combining the results using a bitwise OR operation.

Here are the steps to convert 12-bit data to 16-bit format:

% Assume 'data12bit' contains the loaded 12-bit values
% Step 1: Left shift by 4 bits 
shiftedLeft = bitshift(data12bit, 4);
% Step 2: Right shift by 8 bits 
shiftedRight = bitshift(data12bit, -8);
% Step 3: Combine the results
final16bitData = bitor(shiftedLeft, shiftedRight);

This is a clean and efficient way to scale 12-bit data into a 16-bit format in MATLAB.
