Filter requirements for sensor inputs

[MadhuK]

Hi,

I am designing a signal conditioning board where the analog signals are from various sensors. Some are DC voltages from 0 to 30V and some are AC signals with about 500HZ and 30V ( RMS). Since these signals are from very noisy environment, Please let me know what types of filters to be implemented to better functionality of the board. Please help me with this since I am very new to these kinds of designs.

Thanks in advance.

Regards,

Madhu.

This is such a big question it cant be answered like that. It depends which type of sensors are you using and what you want to achieve using signal processing. Plus what type of signal processing technique are you using.
