What is a decoder? Operation, types and applications
A decoder is a multiple-input, multiple-output combinational logic circuit. It converts the n bit data inputs into the coded 2n outputs. It decodes the information hidden by the encoder. While…
What is Encoder? Operation of Binary encoder and Priority encoder
The encoder is a combinational logic circuit having multiple inputs and multiple outputs. It has 2n inputs and n inputs. The encoder is used to code the information to be…
What is Demultiplexer? Circuit diagram, truth table and applications
Demultiplexer or Demux is a combinational circuit that distributes the single input data to a specific output line. The control inputs or selection lines are used to select a specific…
Implementation of boolean function in multiplexer | Solved Problems
A multiplexer is a digital circuit, which is used to select a single input from the multiple input lines. There are several problems on multiplexer, which are solved to get…
What is a multiplexer? Operation, types and applications
A multiplexer is a combinational digital circuit, which selects and delivers a single input as output from multiple input lines. It performs the similar operation of a switch. Hence, we…
CMOS logic family | NMOS and PMOS
CMOS logic family is a group of logic circuits, built with complementary MOS devices. All the logic gates that are built with MOSFET devices will come under MOS logic family….
Emitter Coupled Logic (ECL)
Emitter-coupled logic is the fastest of all digital logic families. It was invented by Hannon S. Yourke in the year 1956 at IBM. It is also called as current mode logic….
Transistor-Transistor Logic (TTL)
Transistor-Transistor Logic belongs to the digital logic family. It consists of transistors at both input and output side, diodes and few resistors. Unlike Resistor-transistor logic and Diode transistor logic, both…
Diode Transistor Logic (DTL)
Diode transistor logic(DTL) belongs to the digital logic family. This logic circuit has diodes at the input side and transistor at the output side and so the name diode transistor…
