Activity #1: Amplifier

With this diagram as a blueprint to make an amplifier, we arranged our own capacitors and resistors and wires and connected them to an oscilloscope.

The resultant waves illustrates how the voltage is being amplified- the function on top is before amplification and the function on the bottom is after amplification. The bottom function has a noticeably larger amplitude.

Activity #2: AnotherAmplifier

This is an amplifier circuit arranged to amplify sound waves.

We used our phones to test the amplifier, which worked. The sound quality was actually quite good, but still imperfect.
