I have plotted this curve attached below and it seems to be quite distorted in order to analyse it.
How can I smoothen it to analyse it better?

Hi @ekagra gupta
Adding a lowpass filter should filter the high-frequency input signal with normalized passband frequency. For more info, please check the documentation on lowpass():

If you want, you can fit the data to an exponential decay, if you think the underlying physics might follow that model. Demo attached.
