We consider piecewise H¹ functions and vector fields associated with a class of meshes generated by independent refinements and show that they can be effectively analyzed in terms of the number of ...

Abstract: This paper describes piecewise linear circuits operating directly on first-order multi-level and second-order binary sigma-delta modulated signals. The sigma-delta modulated signal sequences ...

Abstract: Piecewise linear (PWL) circuits operating on sigma-delta (/spl Sigma//spl Delta/) modulated signals are proposed. The proposed circuit library includes an absolute circuit, a min/max ...
