TLDR
A new method is proposed with which it is possible to find a delta-modulated signal of the half sum of two analogue signals through a direct operation on their delta- modulated form, leading to the possibility of realization of digital filters with straight delta-Modulated input and output signals which are not intermediately transformed.Abstract:
A new method is proposed with which it is possible to find a delta-modulated signal of the half sum of two analogue signals through a direct operation on their delta-modulated form. With a direct operation it is also possible to form a delta-modulated signal of the product of an analogue signal by a constant. The resulting modulated signal includes an error which is generally considered negligible. The hardware implementation of the method is both, simple and modular employing only conventional full adders and D-flip-flops. This leads to the possibility of realization of digital filters with straight delta-modulated input and output signals which are not intermediately transformed. Multiplexing for changing coefficients is also possible.read more

Mixed-Domain Systems and Signal Processing Based on Input Decomposition
TL;DR: Using input decomposition as a starting point, a variety of new types of systems and signal processors are derived, and their properties are examined, resulting in systems in which signals are processed with a compressed dynamic range and the need for precise nonlinearity control is avoided.

Implementation of delta modulators for digital inputs
TL;DR: It is shown that a delta modulator for digital inputs may be usefully interpreted as a process of slope bias, accumulation, and overflow detection leading to designs which are simpler than those based on analog techniques.
