Here we connect an alterable switch with the NOT gate and the output of NOT
gate is connected to a LED. An LED is an electronic device which will ON and off
when it receives high voltage and low voltage respectively. When the switch is
connected to +5 V, the switch is on position so the LED emits li ght. When the
NOT gate is connected to Ground, the LED will OFF so it doesn’t emit any light.
Pulsed Operation
When we apply a pulse signal to the NOT gate, it will ON and OFF for HIGH and
LOW levels respectively. This means,
