## Decoder Circuit with truth table – Digital Systems

# Technical Studies – Study 28 Introduction Decoders are the combinational logic circuits that intake binary codes, decodes them and produces an output. In other words we can say that decoders are the circuits that perform the opposite operation of Read More …

## Encoder Circuit – Digital systems

#Technical Studies – Study 27 Introduction Encoders are combinational logic circuits that convert numbers and alphabets into coded formats. We can also say that encoder is a logic circuit that performs the reverse operation of decoder. It takes  numbers of Read More …

## Exclusive NOR/X-NOR gate(Equality detector)

#Technical studies- study 9 Introduction The NOTed X-OR is called X-NOR gate. X-NOR is a two input one output digital circuit. It produces a HIGH output all of its inputs either LOW or HIGH. It produces a LOW output when Read More …

## Exclusive OR/X-OR gate(Inequality detector)

#Technical studies- study 8 Introduction X-OR or Exclusive OR gate is a two input one output digital circuit. It gives a HIGH output when only one of its inputs is HIGH. It gives a LOW output when both of its Read More …

## Center taped Full wave rectifier construction and working

#Technical Studies – Study 4 Definition Full wave rectifiers are the circuits those convert an AC signal into pulsating DC signal using the both half cycles of the input signal. Construction: Full wave rectifier uses two diodes, one step down Read More …

## Bridge rectifier wiring with and without filter

#Technical Studies – Study 5 Definition Bridge rectifier is a circuit that uses four diodes in a bridge configuration to produce full wave rectification from AC input signal. Construction: It uses a step down transformer, four diodes, a load resistor Read More …

## What are Universal gates used for?

#Technical studies-Study- 7 Introduction Apart from basic gates there are other two gates using which all complex digital circuits can be simplified. Using these gates the basic gates also can be constructed. The gates are NAND gate and NOR gate. Read More …

## Uses of Logic gates (basic gates)

#Technical studies – Study 6 Introduction Logic gates are the fundamental building blocks of digital circuit. The term logic gate defines that the circuit that able to take decisions. Logic gates give one type of output when certain types of Read More …

## What is Half wave rectifier?

#Technical Studies-Study 3 Rectifiers Rectifier is an electronics circuit that converts AC signal into DC. It is very useful because electronics circuits operate on DC voltage. Rectifier is two types: 1.Half wave rectifier 2.Full wave rectifier Full wave rectifier is Read More …

## DC Circuit – types and uses

#Technical Studies – Study 26 Introduction Electric current always flows in a closed path. That closed path is known as electric circuit. A circuit in which direct current flows is called as dc circuit. In a dc circuit there are Read More …
