Name two applications of decoders. What is the typical usage of the Enable line in a decoder?

Solution

2.Application Of encoder

Encoders are used to take inputs in specific format and to encode them into a another format . For example,we might have an encoder that takes 8 bits of data and depending n the combination of 1\'s and 0\'s give me a specific signal out with 3 bit combination . If I change the 8 bit input I get a different output. It is sort of like a Small memory. Depending on what combination of inputs I \"address\" to it will determine the output.

The enable is control bit for decoder.,acts some what like chip enable.

Also Decoder with enable is working as DeMultiplexer.

The enbale input of a decoder correspond to data input port for Deumx.
