LabVIEWで圧力センサで読み取った値をグラフに表示させたいのですが,無負荷時のときにノイズが出力されてしまいます。フィルタをかけたいのですが,LabVIEWでのフィルタの使い方がよく分かりません。
ブロックダイヤグラムとグラフを添付します。
I'd like to display the value which pressure sensor measure in LabVIEW as a graph, but noise is
output when the sensor does not measure a value. I'd like to introduce a filter, however I don't
know how to use a filter in LabVIEW. I attach the blockdiagram and the graph.
Solved! Go to Solution.

Hi shunki,
noise is output when the sensor does not measure a value.
What is the expected signal/plot for your sensor?
What does the white line (plot0) show?
I'd like to introduce a filter,
Which kind of filter do you need?

Hi shunki,
I guess you tried to use Filter Express VI and got an error message. Filter Express VI need to use the array values for filtering.
If you want to do filtering for the scalar value, you may be able to use Point by Point Filter VI (Functions Palette >> Signal Processing >> Point by Point >> Filters).
By the way, If you want to post as Japanese language, you can do from the following link.
