How can I get the difference between successive quantization levels (i.e. the amplitude of the least significant bit)?

How can I get the difference between successive quantization levels (i.e. the amplitude of the least significant bit)?
If there are some codes, could you tell me?
Thank you

Hey, Chris,
It seems you are interested in determining the amplitude of the least significant bit (LSB) during the quantization process.
The LSB, or quantization step size, can be calculated using the formula:
LSB = (Vmax-Vmin)/2^num_of_bits
In this formula:
  • Vmax is the maximum voltage of the signal.
  • Vmin is the minimum voltage of the signal.
  • num_of_bits is the number of bits used for quantization.
You can refer to the following workaround to accomplish the goal:
% Define the full-scale range of the quantizer
max_value = 5; % Maximum voltage
min_value = 0; % Minimum voltage
% Define the resolution of the quantizer (number of bits)
number_of_bits = 3;
% Calculate the amplitude of the LSB
lsb_amplitude = (max_value - min_value) / (2^number_of_bits);
% Display the result
disp(['The amplitude of the LSB is: ', num2str(lsb_amplitude)]);
The amplitude of the LSB is: 0.625
You can refer to the following documentation to learn more about quantization and ways to implement it in MATLAB/Simulink:
I hope this helps!
