Signals, Systems, and Processes: Understanding Their Interactions
A) Signal
A signal can be defined as characteristic information about any physical event that has occurred or is occurring. These include electric, visual, mechanical, electromagnetic, or even analog and discrete signals, among other classifications assigned by the field of study. The importance of a signal is that it can provide valuable information about an uncertain event, thus enabling prediction and even control.
B) System
A system is a set of interrelated elements that interact among themselves

Integrated Circuits (ICs)
An integrated circuit (IC) is a compact semiconductor device, typically a few square millimeters in size. Electronic circuits are fabricated on this semiconductor material, usually via photolithography. The IC is housed within a protective plastic or ceramic package. This package includes the necessary hardware connections to link the chip to a printed circuit board.
Types of Integrated Circuits
Integrated circuits are categorized into three main types:
- Monolithic Circuits:

The term PLC, widely available in the middle, means Programmable Logic Controller. It was originally called PCs (Programmable Controllers), but with the arrival of the IBM PC, to avoid confusion, we used the acronym PLC definitively. In Europe, the same concept is called PLC. The more appropriate definition is: Industrial System Automatic Control working under a sequence stored in memory, logic instructions. It is a system because it contains everything needed to operate, and industrial by having

Difficulties Generated by the Natural Selectivity of the Stimulus
The following factors can cause difficulties in accurately perceiving sensory stimuli:
- Localization of the observer in space and time: This can cause partial restrictions on the perception of sensory stimuli.
- Imprecisions due to fatigue.
- Selectivity of attention: When multiple stimuli occur simultaneously, only a few may capture the observer’s attention, resulting in a selection guided by the observer’s sensitivity.
- Halo effect: When a
Alternating and Direct Current: Motors and Alternators
Production of Alternating Current in a Rotating Coil
The production of alternating current occurs in a coil that rotates within a magnetic field. Each terminal of the coil is connected to a metal ring conductor, where two brushes collect the induced current supplied to the circuit and determine how it is applied externally. For the induced current, the right-hand rule of three fingers is applied.
Rectifying Current Through the Commutator Bars
We get DC current in the generator output. Converting AC
