This paper presents a configurable CMOS integrated circuit front-end for the recording of a wide range of biopotentials (ExG). The system offers a choice between a single-differential or double-differential recording channel topology, wide continuously adjustable gain range (37–66 dB), selectable CMOS or BJT input stages, offset compensation, differential and buffered single-ended voltage out…
Purpose – Accounting and decision making rely heavily on forecasts. For several reasons, we should expect ongoing increases in forecasting accuracy. The purpose of this paper is to test the hypothesis of improved forecasts over time. Design/methodology/approach – The paper analyzes original monthly sales plans and current data for three different car models in six different countries ov…
