Hi,
Thanks for youق clarification for the word "best"
I'm asking about the best lowest noise & least pass band ripple
My input signal is a frequency it's about 1k Hz
Firstly i'm converting the signal from Frequency to Volt using LM331 after that conversion circuit my signal goes to + or -10...
Hi guys,
I have an Ethernet 16-bit analog to digital DAQ board with 250 kS/s
This's a link for the board

How do i know the best anti-aliasing filter before the analog input?
I'm really confused about this issue i have read a lot...
So What about this red branch
I'm really confused in this circuit
- - - Updated - - -
And why it's a two stage filter ?

Note :
I'm still a beginner in the electronics field, basically i'm a programmer.
Thanks for your help

This's the final drawing after measuring the capacitance could anybody please explain what kind of filter is this ?
In the first part i can see a low pass filter but i don't know what the other part exactly do?

I think the other...
Hi man
I just guess the capacitor capacitance coz it gives me random readings
But thank you for your hint about the cascaded second order low passes coz it's like what i guess too.
If you know anything about the default capacitor values or how can i get it please help coz there's no code...
I'm still not sure about the input signal type coz the signal coming from another board connected to a group of sensors so i'm so confused the signal may be just a frequency coz i think the above image looks like a Sallen-Key second order low pass filter !!! any suggestions
Okay,
It was made by another engineer not by me it takes an analog signal and convert it to VOLTS
I'm asking coz i have to fix it or create another one like it & really don't know what the real purpose of it so i'm asking! about it's function
Many thanks for your reply,
This's the real circuit image
I'm trying to analyse this circuit coz it's damaged & i'm trying to make a new one with the same functions,
So i'm analyzing every thing i can just to make a new equivalent one but with some new modifications
Hi guys,
Can anybody tell me what's this configuration please?
I have found this strange configuration on a strange circuit & i need to know what's the purpose of that?

okay anyway i have exceeded this point by rewriting the code in mikroC & it works well
But i have another problem the program works some times well & gives me the expected results but also some times it gives me unexpected results
i think there's (data loss on the serial bus) AND i don't what...
hi all
I have written the code blew in mikroBasic Pro to drive 4 seven segment
& it works well on Proteus the purpose of code is to make a counter from 0 to 9 on the 4 seven segment
but when i apply it on the real world it does not give me the expected result
also the seven segment are...
