Bruce Reidenbach has almost forty years of professional experience designing custom digital integrated circuits and FPGAs for military ground and satellite communication systems. His early experience used the paper and pencil logic diagram design process. He transitioned to designing exclusively in VHDL in 1994. He retired from full-time engineering in 2018 and currently teaches an introductory VHDL class at Purdue University Fort Wayne. He continues to perform contract FPGA design services, primarily in the area of underwater sensor systems for use by the US Navy. He received his bachelor’s degree in electrical engineering from Purdue University in 1982, and a master’s in business administration from Indiana University Fort Wayne in 1989. In his spare time, the author is a long-time volunteer on-air jazz program host on his local public radio station.
