Electrical Fundamentals for Firmware Developers Questions

Core electrical engineering concepts that firmware developers need to understand and apply when working closely with hardware. Topics include voltage and current behavior, power budgeting and sequencing, ground and reference considerations, power distribution and regulators, decoupling and bypass strategies, impedance and parasitic effects, signal integrity including reflections and crosstalk, thermal considerations, input and output drive capability, level shifting, analog to digital converter and digital to analog converter considerations, electromagnetic interference and electromagnetic compatibility concerns, and practical mitigations such as filtering, shielding, and layout best practices. Candidates should be able to read electrical specifications from data sheets, choose appropriate measurement tools such as oscilloscopes and multimeters, and know when to consult electrical engineers for layout and compliance issues.
