Decimal/BCD Counter. вњЌ Figure 7.6(b). вњЌ Widespread uses in applications where ripple art and craft panchkula The first thing we need to do in designing a 4-bit synchronous counter with D flip-flops is to understand what a synchronous counter is. Synchronous counters differ from ripple counters in that a clock pulse is applied to all flip-flops simultaneously. With this information, we can make our first assumption about our design.A 4-Bit Synchronous Decade Counter. Fig1-14 a synchronous BCD decade counters. Fig1-15 Timing diagram for the BCD Counter table 1-4 States of a BCD decade. 3-Up-Down counter. An up/down (bidirectional) counter is one that is capable of progressing in either direction through a certain sequence. An examination 15 Oct 2011 Objectives. After completing these laboratories, you should be able to: вЂў explain the working of SR and D latches and compare their behaviour with that of an edge-triggered D flip-flop. вЂў construct a toggling flip-flop from a type D flip-flop. вЂў demonstrate a 4-bit, binary ripple counter and design an E6C3 Rotary Encoder (Incremental/Absolute) Datasheet - Advanced
