Experiment 3 - The 4-bit Counter
With four T flip-flops in a chain you build a 4-bit counter.
The inverted output of a T flip-flop is connected
to the input of the next T-flip-flops...

Illustration states of a 4-bit counter.
Each time you press the pushbutton switch S1,
the 4-bit counter counts from 0 to 15,
before it falls back to 0.
Therefore it is referred to as a modulo-16
or mod-16 counter.
The result is displayed as a binary number

In the next experiment,
you get to know more modulo-x counters...
