Built an amplifier circuit to amplify the received wave. However, we used a differential amplifier configuration and it required two sets of voltage dividers (one to offset the signal, and the other one to compare the signal against so that the amplifier will amplify the difference between the two). This isn't ideal since if the DC voltages from the dividers aren't exactly equal, their difference will get amplified as well. Further research was done and we found a non-inverting amplifier configuration that we could bias to be centered at 1.65V (Vcc/2). Below is an excerpt from a MIT OCW guide on biasing amplifiers.
