This thesis is concerned with the analysis and design of an adaptive delta modulator suitable for encoding broadband signals.
A detailed mathematical analysis of the proposed modulator is presented and a closed form relation for the signal-to-noise ratio is derived. The analysis assumes a Gaussian input signal having a flat spectrum.
Finally, the implementation of the proposed delta modulation system is described and experimental results are presented. The circuits were implemented using emitter coupled logic components (E.C.L.).
