Design of a divide by N counter A divide by N counter counter N number of state following which it resets back to the initial state and starts counting again. For example, a divide by 10 also known as a decade counter counts a total of 10 states from 0 to 9 before resetting to...

Sequential-Synchronous Counter Design The different steps for the design of the synchronous sequential counter circuits are: i) State diagram ii) state table and excitation table iii) Simplification using K-Map iv) Logic Design Number of Flip-Flops required for implementing a counter: For N-bit counter, N flip-flops would be required For counter counting upto N states, the number...

Introduction In the previous lectures, you have learnt the Boolean algebra and K-Map methods of solving Boolean expressions. These methods are simple and easy for less number of variables say upto four. But for more than 4 variable equations, these become tedious. So, another method known as Quine Mc-Clusky or Tabulation Method is used for...

Magnitude Comparator

Magnitude Comparator: A magnitude comparator is a combinational circuit that compares two binary numbers and determines their relative magnitude. The schematic block diagram in figure-1 has two inputs and three outputs. It compares two numbers for equality, less than and greater than conditions. Depending on the comparison, one of the output will be true and...

Implementing with Decoders: A decoder is a combinational circuit that converts N-bit binary information to 2N unique output lines. It is able to represent upto 2N distinct elements of coded information. General type decoders usually come in sizes of Nx2N where N is the number of input lines. With a given input, only one of...
