Hi all
I would like to know how to suppress the spectrum of Poisson noise.
At first, I tried "binning". I made the data of Poisson noise which sums up 4Hz sin wave.(the data number##N=10000##,and the data time is 1s) and I average out the data every 100bins. After this, I derived the power spectrum of the data like this.
Second image is the power spectrum without binning.
As you can see, the noise power spectrum isn't suppressed.
All signal (Poisson + sin) are suppressed.
Is this means binning has no effect on Poisson noise??
I would like to know why this happens and how to suppress the poisson noise.
If you can help me, Please.(and sorry for my bad English)
Thank you
