The Kuratowski and Ryll-Nardzewski selection theorem is a classical of measure theory that gives sufficient condition for multifunction to have measurable selection. aim this paper show some generalizations result.

Abstract  In his paper a new current-controlled conveyor (CCCII) in CMOS technology is presented. It features, low supply voltage (±0.7), low power consumption, low circuit complexity, rail to rail operation and wide range parasitic resistance ( ). The circuit has been successfully employed in a multifunction biquad filter. Simulation results by HSPICE show high performance of the circuit and c...
