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
