The parameters design of 1-bit adaptive delta modulations (ADM) systems with uniform sampling rate is well known. Analytical study of delta modulations with sampling rate adaptation have been carried out few years ago. The described ADM systems encode the input signal by changing the sampling intervals and/or step size according to its time-varying slope characteristics. A proposition for design of the parameters of delta modulators with adapting the sampling frequency have been presented. The relation between the boundary values of sampling frequency changes, step size and input power level have been described by the LambertW function. The method presented in this study are useful for parameters design of NS-DM and ANS-DM modulations.
