Analogies and metaphors in analog and digital signals

Abstract

Nowadays, analog, electronic and digital technologies condition the technique that we carry daily, through the use of information and communication transmission and processing devices. From an analog/digital device we can inform ourselves, communicate, organize meetings, exchange goods and services, and a long list of actions that interact from the physical space to the virtual/digital space, and vice versa. This article intends to comment on these transits or tides, using definitions, works of media art, analogies and questions, with the aim to continue thinking about the technology we are holding. First, it asks about the analogy that exists in the analogical signal, then a first transit from the analogical to the digital is briefly analyzed, and the same thing way back: from virtuality to reality.
