Introduction

Electronic systems consist of different blocks which are interconnected. A block diagram indicates which blocks interact with each other. However, in addition to simple indicating which blocks interact, it is possible for a block diagram to indicate the type of signal(s) which connect the blocks.
One way this kind of diagram can be particularly useful is that if each block identifies the type of signals that it requires for inputs and outputs, then it can only directly connect to other blocks providing or requiring those specific signals. In this way, any device added to a diagram implicitly indicates what other devices will also be needed to connect it with some other component.
