beberapa variabel tapi ide pokoknya tidak
diabaikan
Aproksimasi
 Aproksimasi tingkat pertama (ideal)
 Aproksimasi tingkat kedua (tambahan variabel
lainnya)

Electric circuit
 An electronic circuit is composed of individual electronic
components,suchas resistors, transistors, capacitors, inductor
s and diodes, connected by conductive wires or traces
through which electric current can flow. The combination of
components and wires allows various simple and complex
operations to be performed: signals can be amplified,
computations can be performed, and data can be moved from
one place to another.[1] Circuits can be constructed of discrete
components connected by individual pieces of wire, but today
it is much more common to create interconnections by
photolithographic
techniques
on
a
laminated substrate (a printed circuit board or PCB) and
solder the components to these interconnections to create a
finished circuit. In an integrated circuit or IC, the components
and interconnections are formed on the same substrate,
typically a semiconductor such assilicon or (less
commonly) gallium arsenide

Pembagian rangkaian listrik
 Analog circuits

Analog electronic circuits are those in which current or voltage may vary continuously with time to
correspond to the information being represented. Analog circuitry is constructed from two fundamental
building blocks: series and parallel circuits. In a series circuit, the same current passes through a series
of components. A string of Christmas lights is a good example of a series circuit: if one goes out, they all
do. In a parallel circuit, all the components are connected to the same voltage, and the current divides
between the various components according to their resistance.
 Digital circuits

In digital electronic circuits, electric signals take on discrete values, to represent logical and numeric
values.[3] These values represent the information that is being processed. In the vast majority of cases,
binary encoding is used: one voltage (typically the more positive value) represents a binary '1' and
another voltage (usually a value near the ground potential, 0 V) represents a binary '0'. Digital circuits
make extensive use of transistors, interconnected to create logic gates that provide the functions
of Boolean logic: AND, NAND, OR, NOR, XOR and all possible combinations thereof. Transistors
interconnected so as to provide positive feedback are used as latches and flip flops, circuits that have
two or more metastable states, and remain in one of these states until changed by an external input.
 Mixed-signal circuits

Mixed-signal or hybrid circuits contain elements of both analog and digital circuits. Examples
include comparators, timers, phase-locked loops, analog-to-digital converters, and digital-to-analog converters. Most modern
radio and communications circuitry uses mixed signal circuits. For example, in a receiver, analog circuitry is used to amplify
and frequency-convert signals so that they reach a suitable state to be converted into digital values, after which further signal
processing can be performed in the digital domain
Berdasarkan wilkipedia
 Electronics deals with electrical circuits that
involve active electrical components such as vacuum
tubes, transistors, diodes and integrated circuits, and
associated passive interconnection technologies.
 The nonlinear behaviour of active components and their
ability to control electron flows makes amplification of
weak signals possible and electronics is widely used
in information processing, telecommunications,
and signal processing.
 The ability of electronic devices to act
as switches makes digital information processing
possible. Interconnection technologies such as circuit
boards, electronics packaging technology, and other
varied forms of communication infrastructure complete
circuit functionality and transform the mixed components
