A matrix representation method for decoders using the logic gates is proposed, which combines matrix decomposition with majority characteristics. To verify the superiority of this method, a 2–4 and a 3–8 decoders are proposed and implemented in QCA. The proposed decoders have better physical ...
Design of encoder and decoder using reversible logic gates The digital modules are the building block of all the applications in digital world. Encoders and decoders play a vital role in numerous applications. The ... C Kalamani,R Murugasami,S Usha,... - 《Measurement Sensors》 被引量: ...
Apparatus for the secure transmission of digital data signals is disclosed in which fixed logic gates and a variable bank of logic gates are used in an encoding circuit to scramble the digital data signals with two enciphering words. The resulting scramble signals are then further scrambled by a...

A hardware-implemented Huffman decoder converting Huffman-encoded data to raw data using logic gates to implement logic states. The logic states include IDLE, COEFF_READ, COEFF_WRITE, HUFF_ADDR_LOG, HUFF_ADDR_PHY, AMP_CAL, and EOB_RUNGEN. IDLE state transfers to COEFF_READ or AMP_CAL state...
Decoder Logic Decoders can be combined with OR gates to build logic functions. Figure 2.65 shows the two-input XNOR function using a 2:4 decoder and a single OR gate. Because each output of a decoder represents a single minterm, the function is built as the OR of all of the minterms ...
