A signal that does not repeat itself after a specific interval of time is called an aperiodic signal. By applying a limiting process, the signal can be expressed as a continuous sum (or integral) of everlasting exponentials.

In the systems where custom sensors are required, it's imperative that the designer quantifies the environmental, mechanical, electrical, and magnetic parameters of the entire system so that a sensor which meets those operating conditions can be selected.

Whether for cooking or reflow soldering, a thermocouple is often the best choice for a high temperature sensor. The MAX31855, a PICAXE-08M2, a serial LCD, and a few lines of code will do the trick.

To simplify Boolean functions (or switching functions), one might use the Karnaugh map method when there are not that many variables used. However, if a greater amount of variables are used or if several Boolean functions need simplification, using a computer is ideal. The Quine-McCluskey procedure presents a systematic approach that can easily be programmed into a computer for digital simplification.
