Fig. 42: Setup of the binary counter
This circuit of toggle flipflops in sequence is also referred to as an
asynchronous counter or ripple counter. The respective next stage will
only switch with a delay of some nano seconds, which is not visible to
the eye.
14 Stop and Go
Use two open-ended wires instead of the 10 kΩ resistor. The Rx
resistor is then formed, e.g., by touch. Switch the cycle signal on and
off by touching with your finger. You may let the counter run and stop it
by this. Try freezing the outputs right in condition 1. Another option is in
only touching the cycle input. This usually causes a 50 Hz hum to
become active as cycle. This frequency is divided by 4 in total. The last
