Multi-channel Time Interval Counter and fine delay generator
The goal of the project is to create a high-resolution TDC and fine delay generator using only open source software and hardware. We hope this design can become the basis of experimentation and collaboration in a wider community.
Several time interval measurement techniques will be explored in this project. One important family of solutions feeds input pulses into shaping filters followed by an ADC. By time-shifting the acquired waveforms in software, and maximizing correlation between two channels, one can figure out the time interval between two pulses.
Firstly, we made a data acquisition system. To optimise the precision, the transition from the analog to the digital world has to be as clean as possible. It is on this system that the different time measuring elements are added.
