Electronic system:
Any technicalsystem
is an assembly of components that are connected together to
form a functioning machine or an operational procedure. An
electronic system
includes some common
used electrical devices, such as resistors, capacitors, transformers, inductors (choke coils), frames, etc.,
and a few classes of semiconductor devices (diodes, thyristors, and transistors). They are joined to control
the load operation.
