understanding filter

[indrajit]

Hello ALL

                           here with i attached a simple filter vi. Is it correct ..i am not getting the logic... if i change the mode of the filters... anything need to be added.

1. there are two signal 1 and 5

2. applying low pass filter,highpass filter and so..keeping the cut off frequency as same.

Can you attach the vi for lv 8.0? what filtering are you exactly trying to do?

Hi indrajit,

please read the context help for the butterworth filter carefully!

It explains how to wire low/high cutoff freq for the different filter types. Especially the sentence "The VI ignores this parameter when filter type is 0 (Lowpass) or 1 (Highpass)." for the high cutoff freq!

Btw. I wouldn't post my email addresses in a public forum (for SPAM reasons). You will get your answers here without providing the email address...
