    2728||*Used RTL-SDR's to explore software-defined radios (SDR) and tune into local FM stations. \\*Also familiarized ourselves with [https://www.gnuradio.org GNURadio] and its tutorials.||*Learned how to use TI Launchpad MCU MSP-EXP430G2ET. \\*Implemented an adjustable 200kHz-300kHz 50% duty cycle square wave output. Also implemented user input through digital input using the I/O pins. \\*Attempted potentiometer user input, but did not successfully complete it. ||

We also used MATLAB/Octave to compare our results from GNURadio using the SDR.

Learned about matched filters and how to [https://www.telecom.tuc.gr/~aggelos/files/TCOM2014.pdf implement them into the receiver]. We also created a block diagram to illustrate how both the transmitter and receiver should work together to send information about a plant's temperature.\\

Learned 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.
