Synopsis
|
:
|
This course covers some topics in functional electronic
circuits. The circuits are derived from a diverse electronic circuitry
existed in many electronic instrumentation. The function, the behaviour and
the characteristics of the functional circuits are analysed. Design examples
are presented to guide students with the necessary knowledge of how to design
the functional electronic circuits based on certain predetermined
specifications.
