Re: How to meet EMI & EMC standards?
First of all you need to understand how your circuit is working and the the frequencies you need.
Then design it from inside out thinking of removing as much you can of any noise generated from your circuit.
A rule of thumb is that if your circuit don't emit, it will be less susceptible to inbound noise also.
Then you need to add the necessary high voltage/ frequency protection on all in- and outgoing signals.
One of the most critical 'components' are the layout of the PCB, removing any signal loops that can be an antenna for unwanted signals in and out of the circuit.
After your first EMC tests fails, you need to do another round of the above points, and try again.
This goes on until you hopefully get your approvals.
Good luck!

I have one more doubt . How to design circuit to avoid Lighting effect in analog designs.
Because I'm New in these designs.
You'll never make electronics that can take a
direct hit from lightening.
Part of the EMC tests, at least in Europe, is a simulated effect of the lightenig to a degree.
To further help you survive the lightening, you add surge arrestors and different levels of overvoltage protection, normally 3 levels or more.
