What is Priority Encoder ???

* Priority Encoder : The Priority Encoder solves the problems by allocating a priority level to each input. The priority encoders output corresponds to the currently active input which has the highest priority. So when an input with a higher priority is present, all other inputs with a lower priority will be ignored. The priority encoder comes in many different forms with an example of an 8-input priority encoder along with its truth table shown below.

Define Decoder,Encoder ,Multiplexer, Demultiplexer

* Decoder : A binary code of n bits is capable of representing up to 2 n distinct elements of coded information. The name “Decoder” means to translate or decode coded information from one format into another, so a digital decoder transforms a set of digital input signals into an equivalent decimal code at its output. A decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2 n unique output lines. Encoder : An encoder is a combinational circuit that converts binary information in the form of a 2 n input lines into n output lines , which represent N bit code for the input. For simple encoders, it is assumed that only one input line is active at a time. Multiplexer : A multiplexer is a circuit that accept many input but give only one output. Multiplexer means many into one. A multiplexer i...
