Computer Electronics: Digital Electronic Devices (KPI, 2012)
A 195-page lecture text connecting quantization and Boolean algebra to logic families, combinational blocks, latches, registers, counters, and ADC architectures. Its structural logic is durable; electrical limits and implementation technology require current documentation.
The third volume crosses the analog–digital boundary twice. It begins with level/time discretization and ends with ADCs; between them it develops the algebraic and state-machine structures that operate on the resulting codes. That makes it useful as a bridge between sampling, physical logic levels, and clocked digital state.

Engineering contribution #
The enduring design flow is specification → truth table/state table → Boolean or state reduction → structure → electrical and timing verification. A truth table proves only the Boolean relation. A buildable circuit must also meet input thresholds, noise margins, output current, capacitive load, propagation delay, setup/hold time, clock quality, and power-up behavior.
The source's diagrams clearly expose hierarchy. A multiplexer can realize a Boolean function; a decoder plus OR plane can realize canonical sums; a register is a bank of storage elements with shared control; a counter is a state machine whose output sequence implements both counting and frequency division. GTK preserves these connections rather than treating each packaged part as an isolated catalogue entry.
Limits #
- The named TTL, ECL, CMOS, ROM, PLD, ADC, and display-driver parts are period examples rather than current recommendations.
- Contemporary low-voltage interfaces require explicit compatibility checks; family names alone do not establish valid thresholds or drive.
- The source does not develop metastability, clock-domain crossing, static timing, simultaneous-switching noise, signal integrity, or HDL-based synthesis deeply enough for current digital systems.
- Karnaugh maps remain excellent for reasoning about small functions, but automated logic synthesis is the practical path for larger designs.
Visual audit #
All 195 rendered pages were reviewed. Information-bearing visuals include sampling/quantization plots, Karnaugh maps, gate equivalences, transistor-level TTL/CMOS stages, static transfer curves, encoder/decoder/multiplexer block diagrams, flip-flop timing diagrams, register and counter structures, and flash/SAR ADC signal paths.
GTK retains these relationships using truth tables, compact Mermaid graphs, and timing/state tables drawn for article width. The source's Cyrillic rectangular logic symbols are not copied because IEC- and ANSI-style conventions differ; the prose names the Boolean function so symbol convention cannot change meaning. Historical package pinouts and chip-specific timing diagrams are omitted. For transistor-level interfaces, thresholds and fan-out are presented as datasheet inequalities rather than fixed family folklore, and ADC architectures are redrawn around signal flow rather than legacy part internals.
