Circuitos Sintonizados y Transformadores de Redes Selectivas
Juan Carlos Ticse Verastegui, jticsev@uni.pe
RESUMEN: Esta experiencia de laboratorio consiste en
analizar y comparar valores obtenidos en un circuito
sintonizador real con uno teórico.
PALABRAS CLAVE: Sintonizados, tanque, resonancia,
transistores.
I. FUNDAMENTO TEORICO
Los circuitos sintonizados están formados por elementos
reactivos, inductancias, condensadores, líneas de energía,
cristales piezoeléctricos, etc. y se utilizan en los receptores y
trasmisores. Una aplicación típica es en las etapas de
radiofrecuencia de amplificación donde se quiere que el
circuito amplifique solamente una banda de frecuencias.
A las inductancias y condensadores están asociadas
resistencias que se deben a la resistencia ohmicas en las
bobinas y pérdidas dieléctricas en los condensadores que se
hacen más evidentes a altas frecuencias. Podemos modelarlos
suponiendo que son elementos ideales, reactivos puros, con
una resistencia que podemos asociar en paralelo, en serie o en
ambos. Por ejemplo:
Fig. 1. Elementos ideales reactivos asociados a una resistencia
Es interesante relacionar las pérdidas ohmicas y la energía
que almacena como elemento reactivo, lo que nos permite
medir la bondad del componente. El factor de mérito o Q se
define como:
Q= 2π (Energía Almacenada/Energía Disipada por Ciclo)
Para cada caso mostrado da como resultado:
Fig. 2. Factor de Merito para las distintas combinaciones
En el circuito LC hay una frecuencia para la cual se
produce un fenómeno de resonancia eléctrica, a la cual se
llama frecuencia de resonancia, para la cual la reactancia
inductiva (parte imaginaria de la impedancia de la bobina) es
igual a la reactancia capacitiva (parte imaginaria de la
impedancia del condensador). Por lo tanto, la impedancia será
mínima e igual a la resistencia óhmica.
Sea el circuito un RLC paralelo o serie la frecuencia de
resonancia estará dada por:
II. TYPE STYLE AND FONTS
Wherever Times is specified, Times Roman or Times New
Roman may be used. If neither is available on your word
processor, please use the font closest in appearance to Times.
Avoid using bit-mapped fonts. True Type 1 or Open Type fonts
are required. Please embed all fonts, in particular symbol fonts,
as well, for math, etc.
III. EASE OF USE
The template is used to format your paper and style the
text. All margins, column widths, line spaces, and text fonts are
prescribed; please do not alter them. You may note
peculiarities. For example, the head margin in this template
measures proportionately more than is customary. This
measurement and others are deliberate, using specifications
that anticipate your paper as one part of the entire proceedings,
and not as an independent document. Please do not revise any
of the current designations.
IV. PREPARE YOUR PAPER BEFORE STYLING
Before you begin to format your paper, first write and save
the content as a separate text file. Keep your text and graphic
files separate until after the text has been formatted and styled.
Do not use hard tabs, and limit use of hard returns to only one
return at the end of a paragraph. Do not add any kind of
pagination anywhere in the paper. Do not number text heads
the template will do that for you.

Finally, complete content and organizational editing before
formatting. Please take note of the following items when
proofreading spelling and grammar.
A. Abbreviations and Acronyms (Heading 2)
Define abbreviations and acronyms the first time they are
used in the text, even after they have been defined in the
abstract. Abbreviations such as IEEE and SI do not have to be
defined. Do not use abbreviations in the title or heads unless
they are unavoidable.
B. Units
Use either SI or CGS as primary units. (SI units are
encouraged.) English units may be used as secondary
units (in parentheses). An exception would be the use
of English units as identifiers in trade, such as 3.5-
inch disk drive.
Avoid combining SI and CGS units, such as current in
amperes and magnetic field in oersteds. This often
leads to confusion because equations do not balance
dimensionally. If you must use mixed units, clearly
state the units for each quantity that you use in an
equation.
Do not mix complete spellings and abbreviations of
units: Wb/m
2
or webers per square meter, not
webers/m
2
. Spell out units when they appear in text:
. . . a few henries, not . . . a few H.
Use a zero before decimal points: 0.25, not .25.
Use cm
3
, not cc. (bullet list)
C. Equations
The equations are an exception to the prescribed
specifications of this template. You will need to determine
whether or not your equation should be typed using either the
Times New Roman or the Symbol font (please no other font).
To create multileveled equations, it may be necessary to treat
the equation as a graphic and insert it into the text after your
paper is styled.
Number equations consecutively. Equation numbers, within
parentheses, are to position flush right, as in Eq. 1, using a right
tab stop. To make your equations more compact, you may use
the solidus ( / ), the exp function, or appropriate exponents.
Italicize Roman symbols for quantities and variables, but not
Greek symbols. Use a long dash rather than a hyphen for a
minus sign. Punctuate equations with commas or periods when
they are part of a sentence, as in
 
Note that the equation is centered using a center tab stop.
Be sure that the symbols in your equation have been defined
before or immediately following the equation. Use Eq. 1or
“Equation 1, not “(1)”, especially at the beginning of a
sentence: Equation 1 is . . .
D. Some Common Mistakes
The word datais plural, not singular.
The subscript for the permeability of vacuum
0
, and
other common scientific constants, is zero with
subscript formatting, not a lowercase letter o.
In American English, commas, semi-/colons, periods,
question and exclamation marks are located within
quotation marks only when a complete thought or
name is cited, such as a title or full quotation. When
quotation marks are used, instead of a bold or italic
typeface, to highlight a word or phrase, punctuation
should appear outside of the quotation marks. A
parenthetical phrase or statement at the end of a
sentence is punctuated outside of the closing
parenthesis (like this). (A parenthetical sentence is
punctuated within the parentheses.)
A graph within a graph is an inset, not an insert.
The word alternatively is preferred to the word
alternately (unless you really mean something that
alternates).
Do not use the word essentially to mean
approximatelyor effectively.
In your paper title, if the words that uses can
accurately replace the word using, capitalize the u;
if not, keep using lower-cased.
Be aware of the different meanings of the homophones
affect and effect, complement and
compliment, discreet and discrete, principal
and principle.
Do not confuse implyand infer.
The prefix nonis not a word; it should be joined to
the word it modifies, usually without a hyphen.
There is no period after the et in the Latin
abbreviation et al..
The abbreviation i.e. means that is, and the
abbreviation e.g.means for example.
An excellent style manual for science writers is given by
Young [7].
V. USING THE TEMPLATE
After the text edit has been completed, the paper is ready
for the template. Duplicate the template file by using the Save
As command, and use the naming convention prescribed by
your conference for the name of your paper. In this newly
created file, highlight all of the contents and import your
prepared text file. You are now ready to style your paper; use
the scroll down window on the left of the MS Word Formatting
toolbar.
A. Authors and Affiliations
The template is designed so that author affiliations are not
repeated each time for multiple authors of the same affiliation.
Please keep your affiliations as succinct as possible (for
example, do not differentiate among departments of the same
organization). This template was designed for two affiliations.
1) For Author/s of Only One Affiliation (Heading 3): To
change the default, adjust the template as follows.
