Impedance control, crosstalk, and signal Integrity
Special attention should be given to impedance control and relative
adaptation so that the condition of maximum power transfer between
generator and user is always reached.
During routing it is essential to pay attention to critical signals
and treat them properly right away, avoiding crosstalk or crosstalk
problems because it is the electromagnetic field that is generated
in a track when current flows, generates an exchange of energy from
one track to another.
This creates an undesirable disturbance due to the induced spurious
current which affects the quality of the signals which results in a
reduction in communication speed.
A good digital signal has fast transitions and logic levels that
are clean and free of transient phenomena.
The circuit diagram is a diagram showing circuit connections within
a code of a circuit element.
Schematics are a type of schematic layout of components and their
relationships drawn with physically and electrically standardized
symbols for research and technical planning.
Schematics can convey the working principles of components, analyze
their performance, and provide a planning system for installing
electronic and electrical products.
In the circuit design, the technician can settle on paper or a
computer after confirming that the actual installation is complete.
Improve, fix, and succeed through debugging.
Using circuit simulation software for circuit-assisted design and
virtual circuit experiments can improve the work efficiency of
engineers, save learning time, and make real pictures more
intuitive.
Parts in the circuit do not necessarily resemble or completely
different in shape from the actual parts.
However, it generally represents the characteristics of the
element, and the number of pins matches the actual element.
Like many wires in radio schematics, they are not necessarily
straight in the printed circuit board diagram, but they can also be
copper films of a particular shape.
A node represents a connection between multiple pins or wires.
All pins and conductors of the components connected to the node are
conductive, no matter how many.
Annotations are very important in schematics and all text in the
schematic can be categorized as annotations.
If you look closely at the figure above, you can see that there are
annotations in various parts of the schematic. Annotations are used
to indicate the type, name, etc. of a component.
