In this video we will take a look at the LM567 Tone Decoder Integrated Circuit. In this on the bench demo we will set an LM567 to detect a 400 Hz signal and light an LED. We will also examine the behaviour of the IC on the Oscilloscope measuring the logic level output from high to low under frequency detection.
We will also test a project board i built using the LM567 using a Function Generator as a signal source.
