    43 //Receiver: //Explored the accuracy of the receiver while changing the power transmission, frequency, and distance between the SDR and signal generator. Introduced about matched filters and how to [https://www.telecom.tuc.gr/~aggelos/files/TCOM2014.pdf implement them into the receiver]. Despite a frequency measurement error, we implemented logging into GNURadio using a file sink.

    61 //Progress: //We moved the bench to on top of an antistatic mat. We also implemented twisted pair cables and an external DC power supply. All of these changes were made to get cleaner signals and avoid accidental antennas. We also made major progress on our work, being able to measure voltage across a Wheatstone bridge (see below) and encode it as a backscattered signal between 100kHz and 200kHz.
