EE200 DIGITAL LOGIC CIRCUIT DESIGN Class Notes CLASS 14-2&3 The material covered in this lecture will be as follows: Ripple counters. ± Binary ripple counter. ± BCD (Decimal) ripple counter. After finishing this lecture, you should be able to: Describe the operation of binary ripple counters. Recognize the count cycle and timing diagram of counters. Understand the modifications required for the input functions to transform the 4-bit binary ripple counter to BCD ripple counter. ipple Counters R here are two categories of counters: T ² Ripple counters, ² Synchronous counters. Ripple counters are counters where each flip flop is triggered by the transition of other flip-flops. In synchronous counters all flip- lops are triggered by the same clock pulses. f inary Ripple Counter EE200(class 14-2&3) Prof. M.M. Dawoud 136 B
