ipomap IPOMap is an open-source visualization tool designed to help you map and analyze workflows using the Input–Process–Output (IPO) model. Each element—inputs (documents, databases, files), ...

The aim: Create a 3.3V source from a –5V supply. You can obtain a precise, positive-output voltage from a negative-voltage supply with a boost converter and a linear regulator. The input and output ...

Block diagrams are clear, simple diagrams showing all of the input, process and output elements that make up the system being designed. They are easy to read and show how the circuit will work.

Process devices take the signal from the input stage of a system and act on it by changing it in some way. Transistors are an example of a processing device, and are a special type of switch.
