Start Date and Commitments

Start:10/10/2023 - 10 lectures on Tue 11-12, Wed 12-13

Extra lectures on 16/10/23 and 23/10/23 both 12-13

Module Details

To provide an introduction to digital circuit design with particular regard to programmable logic devices, such as FPGA (Field-Programmable Gate Arrays). FPGAs are nowadays a fundamental element of data-acquisition systems in all the main particle physics experiments.
