Hi Everyone:
- I am using NI-9220 and NI 9203
- am acquiring continuous analog (current) data signal from Laser Distance Sensor.
- To acquire measurements, I used DAQ assistant.
- I added the shift register to save the acquired data from the previous loop.
- I did add Three step filtration:
- Backward/Forward Filter to fix the phase shift problem
- Low Pass Filter
- Moving Average
The vi software is attached.
Questions
- Could you please review the vi software and let me know if there is anything wrong? It seems to me that there is something wrong
- How can I get the average (Arithmetic Mean) in one point every 100 points instead of the moving average? In other words, I want only one averaged a point per second at the end of every iteration.
- How can I add another different channel in the same loop but with different parameters such as sampling rate, signal type (voltage), and apply the filtration process in the same loop?
- How can I make increase the precision of the measurements?
Any recommendation, suggestion, any help would be highly appreciated.
Thanks
