0 a piece of equipment that allows you to receive particular television signals:
You need a decoder to get these channels.
1 a piece of equipment that changes electronic signals into a form that can be used by other equipment, for example a television:
On top, clients need interfaces to generated encoders and decoders.
At post-test, all intervention group children were better decoders, and had better phonological awareness and letter-sound knowledge than controls.
This shows one of the eight decoder channels, omitting the others for clarity.
In words, this is the channel error probability for which the 'maximum-likelihood decoder' defined above fails with probability 1/2.
Clearly, children who were classified as good readers were much better decoders than children who had been classified as poor readers.
Finally, decoders are annihilated by their duals when a generalised sharing has been completely decoded.
In fact, an "encoder" network is a combination of encoder and decoder.
This is why occurrences of variables are marked with the dual decoder when they are linked by a coded abstraction.
