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.

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 input and output capabilities of the circuit in Figure 1 depend on the allowable I/O voltages of IC1 and IC2. In this case, IC1 and IC2 convert a –5V input voltage to a 3.3V output voltage. Read ...
