Module 4: Complex Combinational Circuits

A combinational circuit is a circuit where the current state of the circuit depends only on the current inputs, and not on the previous state of the circuit. This can be compared to sequential circuits, where the output of the circuit may depend on the previous state of the circuit.

For instance, counters and registers are considered sequential circuits, whereas BCD to 7-segment display decoders are combinational circuits.

Throughout this module, we will be exploring more complex combinational circuits that you may use in future projects. This will include things like multiplexers, binary comparators, priority encoders, and so on. We won't touch upon adders, as those will be covered in the next module.
