Johnson Noise is electrical noise found across a resistor when no current is present. Johnson Noise occurs due to the thermal fluctuations affecting the metal in the resistor. During sixth block, a Johnson Noise detector was built in an attempt to isolate Johnson Noise from all other electrical noise, thus laying the groundwork for future projects in secure communications.
