Real time filter of Analog Input to Output

[zyz]

Hello,

I used the Network Analyzer on Analog Discovery 2 to measure the transfer function of a system and it was quite handy. I was wondering given this filter information, does the device allow a easy-to-implement real-time application of this filter to the analog input and simultaneously feed the filtered data to the output? 

Thanks!

Hi @zyz

The WaveForms application does not support such.
You could create a custom application or script to stream data from scope (analog-in), process it and stream to wavegen (analog-out).
This should work with up about 200-500kHz sample rate and have a delay of 10-100ms
See the AnalogIn_Record.py and AnalogOut_Play.py examples.

@attila Thanks for your answer! Could you kindly provide a link to these examples?

Hi @zyz,

The examples can be found in the WaveForms installation. On my windows machine this is in: C:/Program Files (x86) -> Digilent -> WaveFormsSDK -> samples -> py

Thanks,

Hi @zyz

You can also find shortcut to the SDK in the Start menu/ All programs/ Digilent/ WaveForms SDK
or press the SDK button in the WF application.
