What are the principles of signal theory?

The principle idea of signal theory is that to maintain a connection between two peers, the connection must be held by a small amount of data constantly being sent and received between the two devices, pinging backwards and forwards.

What is the most common distinction of signal types?

Signals can be categorized in various ways. The most common distinction is between discrete and continuous spaces that the functions are defined over, for example, discrete and continuous-time domains. Discrete-time signals are often referred to as time series in other fields.

What are the 3 major categories of signals?

Forms of signaling

There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine signaling, endocrine signaling, and signaling by direct contact.
