Internally, these decoders look very much like the circuits above. Here's one of the 1-of-4 decoders. Notice how NAND gates are used instead of ANDs as I've used above. That's why decoder output are typically a
The two transistor circuits are formed in separate substrates, one substrate being a well formed in the other substrate, or both substrates being wells formed in a third substrate. The substrate of the first transistor circuit is biased at a higher potential than the substrate of the second ...

Thus, the main burden for implementing the check node operation consists in finding the first and second minimum of the incoming messages together with the position of the first minimum. High-speed circuits for finding the first two minima have been addressed in, e.g., [47,48]. A simplified...
a seven segment display is used to display both the numbers and characters. These displays are frequently driven by the output phases of digitalintegrated circuitslike decade counters as well as latches. However the outputs of these are in the type of 4-bitBCD (Binary Coded Decimal), so not...
In this paper, we propose a layered decoder to decode quasi-cyclic multi-edge type LDPC (QC-MET-LDPC) codes using a graphics processing unit (GPU) in continuous-variable quantum key distribution (CV-QKD) systems. As described herein, we optimize the storage methods related to the parity ...
radios generally need to at least eventually make a "hard" or firm decision identifying each received symbol--since the radio's audio processing circuits need a definitive signal as opposed to an output saying "I don't know" or "I'm not sure." However, the stage at which this "hard" ...
As is well known, decoder circuits generally function to decode one digital signal and to transform it into another digital signal. In a semiconductor memory, decoder circuits decode memory addresses for selecting a desired word line and bit line to obtain access to the specific memory cell at ...
