from the highest potential point to the lowest one. Although,
usually the direct current is identified with the constant cur-
rent (for example the one supplied by the battery), it is con-
tinuous any current that always maintain the polarity.
• DSP.- It is the acronym of Digital Signal Processor. A DSP is
a system based on a processor or microprocessor that has
instructions in it, a hardware and an optimised software to
develop applications where numerical operations are needed
with very fast speed. Due to this, it is very useful to process
analogical signals in real time: in a system that runs in this
way (real time) samples are received, usually coming from an
analogical/digital converter(ADC).
• Power factor.- It is defined as power factor, p.f., of an alter-
nating current circuit, as the ratio between the active power,
P, and the apparent power, S, or as the cosines of the angle
that make the current and voltage vectors, designating as
cos
f
, being
f
the value of that angle.
• GND.- The term ground, as its name states, refers to the po-
tential of the earth surface.
• EMI filter.- Filter able to decrease the electromagnetic inter-
ferences, which is the perturbation that happens in a radio
receptor or in any other electrical circuit caused by the elec-

9.2. Glossary.
• AC.- It is nominated as alternating current (abbreviation
in Spanish CA and in English AC) to the electrical current
in which the magnitude and direction varies in a cyclic
way. The most common wave shape of the alternating
current is sinewave, because the energy transmission
is better. Nevertheless, some applications could need
other period wave shapes, like triangular or square
• Bypass.- Manual or automatic, it is the physical junction be-
tween the input and the output electric device.
• DC.- The direct current (CC in Spanish, DC in English) is the
continuous electron flow through a cable between two points
with different potential. Unlike the alternating current, in direct
current the electrical loads always flow in the same direction
