Conventional multiplexer switches hava an annoying disadvantage that the video signals mix over when the source is changed but this circuit avoids this problem by disabling the inactive signal line.

3x8Decoder.bbrd – A 3-to-8 line decoder circuit. 8X3Encoder.bbrd – An 8-to-3 line encoder circuit. DEMUX.bbrd – A demultiplexer circuit for signal routing. MUX(4-input).bbrd – A 4-input multiplexer ...

We won’t go into this in detail here. Suffice it to say that we ended up with the truth table and circuit diagram illustrated below: Earlier, we noted that we can use the CD4512’s 8:1 multiplexer to ...

Ternary logic is a promising alternative to conventional binary logic, since it is possible to achieve simplicity and energy efficiency due to the reduced circuit overhead. In this paper a methodology ...

VHDL implementations of combinational logic circuits, including a simple ALU, multiplexer, and seven-segment decoder. Uses structural and dataflow coding styles with Quartus Prime and ModelSim-Altera ...
