(Solved): Change the MOD-8 counter in Figure to a MOD-16 counter, and connect the MSB to the multiplexer E in ...

Expert Answer

To modify a MOD-8 counter into a MOD-16 counter, we need to add an additional flip-flop to increase the number of states from 8 to 16. This new flip-flop will be connected to the output of the existing MSB flip-flop, effectively adding an additional bit to the counter. The connections between the flip-flops will need to be modified to ensure that the counting sequence follows a MOD-16 pattern.

Once the MOD-16 counter is constructed, we can connect the MSB output to the multiplexer E input. This will allow us to select between the MSB output and the final bit of the counter, depending on the state of the select input.

Here is an example schematic of a MOD-16 counter with a multiplexer connected to the MSB output:


In this schematic, FF-1, FF-2, and FF-3 represent flip-flops, and MUX represents a multiplexer. The MSB output from FF-3 is connected to the select input of the multiplexer, and the Z output is taken from the output of the multiplexer.
