Hello. I need your advice. I have a signal with some values 1,5 2,1 3,4 and so on.
I want to simulate the quantization of signal for some digit capacity.
For example 5 V and 8 bit. It will 5/(2^8-1) and one step in column X i*0,0196;
After that I need to round values of signal to this nearest digital values so
1,5 = 1,5092 2,1 = 2,0972 3,4 = 3,3908 etc.

Hi Donyck1,

Please try the following formula in the Set Column Values tool for column B
(5/(2^8-1))*round(col(B1)/(5/(2^8-1)))
Does it work?
