(A) Clocked R-S (B) J-K

This document contains a student's answers to assignment questions about digital electronics and flip-flops. The student provides logic symbols for clocked R-S and J-K flip-flops, truth tables for D and R-S flip-flops, examples of devices built using J-K flip-flops, and logic diagrams for a mod-10 counter and divide-by-8 counter using a 7493 IC. The student also identifies "ripple counter" as another name for an asynchronous counter.
