Astable Multivibrator using 555 Timer
The 555 timer generates the continuous pulses in astable mode with specific frequency that depends on the value of the two resistors and capacitors. Here the capacitors charges and discharges…
What are Decoders?
Decoders are digital ICs which are used for decoding. In other words the decoders decrypt or obtain the actual data from the received code, i.e. convert the binary input at…
What are Encoders?
Encoders are digital ICs used for encoding. By encoding, we mean generating a digital binary code for every input. An Encoder IC generally consists of an Enable pin which is…
Common Digital ICs used in digital logic circuits
Given below is a tabular form of the summary of CMOS and TTL digital ICs used in most of the digital circuits. We hope our article has been informative in…
Sequential digital logic circuits
A Sequential digital logic circuit is different from combinational logic circuits. In sequential circuit the output of the logic device is not only dependent on the present inputs to the…
Combinational logic circuit
Combinational digital logic circuits are basically made up of digital logic gates like AND gate, OR gate, NOT gate and universal gates (NAND gate and NOR gate).All these gates are…
Analog and Digital Circuits
Analog Electronics Most of the fundamental electronic components – resistors, capacitors, inductors, diodes, transistors, and operational amplifiers – are all inherently analog. Circuits built with a combination of solely these…
Relays
A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. Relays are found hidden in all sorts of devices. In fact, some of…
Truth Table Practice Problems
C. Build the following circuits and prove their correctness using truth tables: 1. Build a circuit that simulates a NAND gate using only AND, OR, and NOT gates. You need…
Truth Tables
Truth tables are a way of figuring out how a particular digital circuit will respond to different inputs. Truth tables have two distinct parts: each left hand column is labeled…
