What is Level Triggering
In the sequential circuit, if the output changes during the high voltage period or low voltage period, it is called level triggering. In other words, the output changes during either…
Analysis and Design of Combinational and Sequential circuits
1. Analysis and Design of Combinational circuits: To design of combinational circuits, the procedure involves the following steps: 1. Find the required number of inputs and outputs and assign a symbol to…
Construction of Combinational Circuits
A Combinational Circuit consist of logic gates whose outputs at any instant of time are determined directly from the present combination of inputs without regard to previous input. Examples of combinational circuits:…
Switch Debounce in Digital Circuits
We all know how a switch or a push button works, you simply press it to toggle its state. In electronics, switches are used to drive or represent many things,…
Combinational and Sequential Circuits
A Digital logic (or Switching) circuit has voltage levels to be switched from one value to another but has a finite number of distinct values (generally 0 for false and…
Difference between Synchronous and Asynchronous Sequential Circuits
Sequential Circuits are those which have the notion of an internal state. This notion of Internal State is necessary because in sequential circuits, the output of the circuit is function of both the present…
Asynchronous Sequential Circuits
Asynchronous Counters Let us recall what a counter is. A counter is nothing but a sequential circuit that experiences a specific sequence of states when certain input pulses are applied to the…
Synchronous Sequential Circuits in Digital Logic
Steps to solve a problem:1. Draw the state diagram from the problem statement or from the given state table. Example: Serial Adder.The functioning of serial adder can be depicted by the following…
Code Converters
Numbers are usually coded in one form or another so as to represent or use it as required. For instance, a number ‘nine’ is coded in decimal using symbol (9)d.…
Classification of Combinational Logic
One of the most common uses of combinational logic is in Multiplexer and De-multiplexer type circuits. Here, multiple inputs or outputs are connected to a common signal line and logic…
