Experiment 16 - The astable Multivibrator using Schmitt-Trigger

In the circuit shown, you use the Schmitt-Trigger NAND gates of a C-MOS 4093.

Circuit of an astable multivibrator of Schmitt Trigger. (Enlarge)

Circuit diagram of an astable multivibrator of Schmitt Trigger.

If you connect the battery, the LED begins to flash.

Surely you realize the similarity to the astable multivibrator of NOT gates. However, using Schmitt Trigger compensates for some of the disadvantages.

In the next experiment, you change the astable multivibrator a little bit...
