EMC

Akhir-akhir ini aku agak sibuk dengan kerja terutama EMC test.
Apa itu EMC??
Meh aku ceritakan secara copy and paste dr note hahahhaahaa

EMC stands for Electromagnetic Compatibility. The term EMC has 2 complementary aspect:-
- the ability of the system to operate without interfering with other systems
- the ability of the system to operate as intended wihtin a specified electromagnetic environment

There are 3 essential elements to any EMC problem
a) Source - a source of an electromagnetic phenomenon, e.g.: radio transmitters, power lines, electronic circuits and etc.
b) Transmission path - a path that allows noise to transfer from the source to the receptor.
c) Victim / receptor - the victim that cannot function properly due to the electromagnetic phenomenon.

The 2 common transmission methods: -
a) Conducted - through external cables, power cords or I/O interconnector.
b) Radiated - by air or via free-space propagation.

Kita buat EMC test ini untuk memastikan product yang kita design itu tidak merbahaya leee...senang cerita
Contohnya, walaupun ada radiation tapi pada kadar selamat digunakan oleh manusia.
Begitulah serba sedikit

Kita juga hendak memastikan product yang kita design itu tahan pada EMC.
Contohnya kat area yang ada GSM etc tu, kita nak pastikan product kita mampu beroperasi walaupun ada gangguan.
begitulah serba sedikit lagi.
sekian
