Gate questions on sequential circuits pdf
A sequential circuit is said to be synchronous if the internal state of the machine changes at specific instants of of time as governed by a clock. Circuits with an acyclic underlying topology are combinational. Feedback (cyclic) is a necessary condition for a circuit to be sequential. Clocks in Synchronus Sequential circuits Can someone illustrate with well defined procedure of finding the output timing diagram in the circuit involving various flip flops, some combinational circuit. This circuit should be synchronous i.e., being run by a single clock?
Computer Science Engineering (CSE) Combinational & Sequential Circuits Summary and Exercise are very important for perfect preparation. You can see some Combinational & Sequential Circuits sample questions with examples at the bottom of this page.20. Design the clocked sequential circuit using JK flip-flops whose state diagram is given below. (16) 21. What is the use of State reduction? Reduce the state diagram. (10) 22. Design 4 bit synchronous counter using X-OR gate as well as JK Flip-flop to count from 0 to 15. (16) 23. Distinguish between synchronous and asynchronous sequential ...Circuit inputs inputs of others. The circuit as a whole has one or more inputs, each of which can and outputs be inputs to various gates within the circuit. The outputs of one or more gates are designated circuit outputs. If there is more than one output, then an order for the output gates must be speciﬁed as well.

This note covers the following topics: Number systemand codes, Boolean Algebra and Logic gates, Boolean Algebra and Logic gates, Combinational Logic, Synchronous Sequential logic, Memory and Programmable logic, Register Transfer levels, Digital Integrated logic Circuits.
used to derive circuit equations from existing sequential circuits are not generally covered in existing texts and appear to be unknown to many designers. For some readers this section will provide a useful complement to the core material. I wish to thank Frank Brown for his many suggestions which have resulted in a materially improved paper.
