how to make a program to filter (lowpass) the waveform from my initial waveform

[sabaukusauso]

hye,

i have got the EMG data to display at waveform graph. what i want to do now is from that waveform, how to make a program to filter it by using lowpass filter. from the new value of waveform i want it able display to txt format. i have already doing selected the Express Filter function as well as the functions on the Signal Processing>Filters palette, i do not have any idea how and where to connect the my own data to filter it after i has select Read From Measurement File. i have try many times, but i got no idea. can you give me the tip or program like i want. thanks

Do not start a new thread for a question you have already asked - and gotten an answer for. If you are still confused, post your code and file and do that to the original thread you started.

morning, hye dennis, i am sory what i am done before.

here, i attached the emg data i have get and the program like yours said to do it.  actually i already get do to view waveform from my EMG data signal, after that, i want to filter the waveform signal i get by usinglowpass filter and also want view the new waveform after filter it. and then, i want the new dataenter in txt format. ihope you can help me. thanks

In the 'express filters', you show how a filter is connected to the Read From Measurement File and then displayed in a graph so your question does not make any sense to me?

p.s. Attaching images of code is not the best idea unless you attach a snippet (LabVIEW 2009). No one can debug an image and Express VIs hide way too much code to be able to diagnose any problems.

Why don't you just simply wire your signal to filter express vi, and wire its output to write to measurement file vi?

I don't see any difficulty doing so.

hye dennis,
actually i already upload the program,but during i click send, the error about not suitble format appeared. so, i think why format .vi can not sen in this email also file in .lvm. actually i want really to show you what im done.

How are you trying to attach the files. Are you not using the 'Add Attachments' option? It's right below the message body.

[sabaukusauso]

[sabaukusauso]
