With the continually increasing need for transmission of digital data over noisy channels, need for error control and correction techniques are also raising as well. There are various techniques and methods available for transmission of digital data over noisy channel but Viterbi Decoder is most efficient .It provides better coding gain at lower cost and good performance Convolutional encoding ...

By a combination of graphene oxide and DNA, a universal platform was developed for integration of multiple logic gates to implement both half adder and half subtractor functions. A constant undefined threshold range between high and low fluorescence output signals was set for all the developed logic gates.

A cellular logic system capable of combinatorial and sequential logic operations based on bacterial protein-triggered cytotoxicity was constructed. Advanced devices such as a keypad lock, half-adder and several basic Boolean properties were demonstrated on the cells.
