Digital Electronics - Combinational Logic Circuits

An encoder in which the highest and lowest value input digits are encoded simultaneously is known as a priority encoder.

Three select lines are required to address four data input lines.

Single looping in groups of three is a common K-map simplification technique.

In true sum-of-products expressions, the inversion signs cannot cover more than single variables in a term.

A combinatorial logic circuit has memory characteristics that "remember" the inputs after they have been removed.
