The digital electronics section of the unit includes an examination of simple logic gates and applications including the description of circuit operation in truth table form, the derivation and manipulation of Boolean equations along with the Karnaugh Map reduction technique. Circuit implementation techniques using simple logic gates and universal gate sets are examined along with simple asynchronous (ripple) counting circuits. Student designs are tested in logic simulation software and implemented on Field Programmable Logic Arrays (FPGA).

The analog electronics section of the unit involves the study of PN and Zener diodes and their electrical characteristics and applications. The small signal equivalent circuits of Bipolar and MOSFET are introduced along with applications including the analysis and design of single stage BJT and CMOSFET amplifier circuits and linear and switching power supplies.
