How do you overcome the limitation of delta modulation?

To overcome the limitations of delta modulation, such as slope overload and granular noise, one can implement adaptive delta modulation (ADM), which adjusts the step size based on the signal's characteristics. Additionally, using predictive coding techniques can enhance performance by anticipating changes in the signal and optimizing the modulation process. Employing filters to smooth the output can also help reduce noise and improve the overall quality of the signal reconstruction.
