In statistics it is common to require a simple approximating equation for a smooth relationship between Y and X. The exact mathematical form may be known (but complicated) or unknown. We show that ...

Lookup tables and Taylor series are two common methods for interpolating between experimentally gathered data or for generating a known function such as a sine wave. This article proposes a third ...

[Igor] made a VU meter with LEDs using 8 LEDs and 8 comparators. This is a fast way to get one of 8 bits to indicate an input voltage, but that’s only the equivalent of a 3-bit analog to digi… ...

Then customers wanted systems that worked with real-world data. Floating point reared its very ugly head. Anyone can do integer math in assembly, but floats are tough indeed. Possibly the first ...
