An Interview with Dr. Howard Johnson - Winsome Waveform Wizardry
Dr. Howard Johnson, author of 'High Speed Digital Design: A Handbook of Black Magic' and a high-speed signal integrity consultant, discusses the evolution of signal integrity, the importance of mentorship, and the practical realities of designing high-speed systems. He explains how adaptive equalization works, the limitations of cheap cables, and why right-angle PCB traces are less problematic than often believed. Johnson also shares insights from his work on Ethernet standards, his teaching at Oxford University, and the historical progression of communication technologies from binary to multi-level signaling.
