Controller Logic Design
I revisit my VHDL sources, schematics, and waveforms from combinational logic through finite-state machines.

Electrical Engineering Coursework
Separate course hubs with twelve study units for each electrical-engineering subject.
Course Hubs
Separate subject pages
Electronic Circuits I
I organize a study path from diodes to single-transistor amplifiers in the order that makes the circuit behavior easiest to revisit.
Electronic Circuits II
I study differential stages, feedback, filters, and output stages as one connected signal path.
Digital Communications
I use the saved course file to reconnect sampling, baseband transmission, digital modulation, and error-rate analysis.
Automatic Control
I follow the saved course materials and calculations from modeling through stability, root locus, and frequency response.
Applied Control Engineering
I use the saved simulation video as a starting point to revisit state-space control, observers, and digital control.
High-Frequency Engineering
I revisit transmission lines through Wilkinson and branch-line networks using my assignments, Cadence circuits, and S-parameter figures.
Power Electronics
I organize a study path from switching devices to converters and inverters while tracking power flow and device stress together.
Electrical Machines
I revisit magnetic circuits, transformers, and rotating machines around my transformer report and calculation sheets.
Motor Control
I use my PSIM report and PI calculation file to revisit the DC-motor model, cascaded current-speed loops, and field weakening.
Embedded Systems
I keep university coursework, personal STM32 study, research F411 acquisition, and Raspberry Pi projects as separate records.
