I have some experimental data, and since the measurements are digital, the data is discretized/quantized/rounded/truncated.
I need to know if there are general methods, or common methods, to "smooth" the data, remove the discretization, or identify what type of distortion it has (rounding is not the same as truncation or quantization)
I can invent some things, like assuming that data is truncated, and doing interpolations, or using regression to smooth the data, but I don't want to reinvent the wheel and make novice mistakes.
I guess that this is a common problem with measurements, so there must be a set of techniques generally used on experimental physics. Where should I look for them?
