Background :

Counter circuits are used in digital systems for many purposes. They may count the number of

occurrences of certain events, generate timing intervals for control of various tasks in a system,..

The simplest counter circuits can be built using T flip$-$flops because the toggle feature is naturally

suited for the implementation of the counting operation.

Counters could be synchronous or asynchronous depending on how the clock are connected for each

flip flop.

We are interrested in the synchronous binary up counter. Specifically, the following table shows the

contents of a $3$ bit counter for $8$ consecutive clock cycles.

Now, when we observe each row of the table, it is clear that bit $Q_0$ changes on each clock cycle. $Q_1$

changes only when $Q_0=1.Q_2$ changes only when both $Q_1$ and $Q_0$ are equal to $1.$ Task :

$1.$ Determine from the above description, the equations of T inputs for each T flip flop used in the

design of the counter.

$2.$ Design the circuit for a $4$bit up$-$counter using T flip flop

Specify the equations for each T input.
