Summary A mathematical model for linear adaptive level‐based sampling is developed in this paper. The proposed mathematical model provides a gradual change in quantization size and maintains time difference between two successive samples greater than or equal to loop delay of the system. This model is developed to minimize signal slope overload distortion as well as reduction in quantization noise. The proposed mathematical model is demonstrated in MATLAB simulation environment. Simulation results are compared with level‐based sampling and adaptive level‐based sampling based on bit‐level compression. Copyright © 2015 John Wiley & Sons, Ltd.
