I have an electronic and electrical engineering degree. I have extensive working experience in electronics. I worked on radar and digital signal processing and in particular in implementing a range tracking loop. The loop was implemented with two Intel 2920 signal processors running in conjunction with each other. The programming was done in Assembler. I was further involved in several other electronic projects. I also have experience in other embedded systems. I have some knowledge of C and the use thereof in the programming of the Pic family of microcontrollers. I have done work in C++, Visual Basic and Python. I did several Arduino projects. I have experience in LT Spice simulations and KiCad PCB design software.
