Progress during week two:

The first amplifier was built using an LM386, we had decided to work on the poster as well as the two other amplifiers, the OPA2134PA and OPA134PA. It was then later realized that the two remaining amplifiers were the same so only one more was built. We had used two AC inputs for the OPA2134PA, simulating stereo and we managed to get a gain of 2. We connected the speaker to the circuit that Conor had built,  and proved that the audio was being amplified as the amplitude/frequency was being changed. During this week the blog was also started 

 

Goal for week three:

• Further assess the circuit Conor built to find more possible mistakes
• Build one more circuit
• Simulate circuits on Multism
• Connect phone to the speakers to properly test the audio
