Source:- Digital Logic (KEC Publication ) Design Moore sequence detector to detect a sequence —-101-using D F/F A sequence detector is a sequential state machine. In a Moore machine, output depends only on the present state and not dependent on the input (x). Hence in the diagram, the output is written with the states. The […]

Types of codes BCD (Binary-Coded Decimal) code : Four-bit code that represents one of the ten decimal digits from 0 to 9. Example – (37)10 is represented as 0011 0111 using BCD code, rather than (100101)2 in straight binary code. Thus BCD code requires more bits than straight binary code. Still it is suitable for input and […]

 Counter A counter by function is a sequential circuit consisting a set of flip-flops connected in a suitable manner to count the sequence of the i/p pulses presented to it in digital form. Counters are fundamental components of digital system.  Digital counters find wide application like pulse counting, frequency division, time measurement and control and timing operations. There […]
