    v32 v33  
    3636 * Began sending digital waveforms with modulations (so they could actually carry information) using GNUradio and the benchmark_tx and benchmark_rx programs
    3737 * Tested out the differences between various modulations and sampling rates using the programs rx_ascii_art_dft to see the waveforms and benchmark_rx to note the quality of the transmission (See picture)
    38  * Found the limits of the b210 USRPs (the physical radios) at certain modulations in terms of the maximum sampling rate they could handle before underwriting (found the limits of the hardware) (See picture).
    39 *Began learning Bash to write my own scripts.

    … …  
    4344* Authored another program to cycle through various modulations and sampling rates, parse the output for the final line with the results, and write that into a file
    4445* Researched more about benchmark_tx and benchmark_rx to better understand the output
    45 * Plotted the results in MATLab for each modulation, comparing the sampling rate of the transmission vs the number of successfully received packets of data ^([#hn Image 4])^
     46* Plotted the results in MATLab for each modulation, comparing the sampling rate of the transmission vs the number of successfully received packets of data. See picture.
    4647* Varied other factors such as tx gain and the packet size (a total of 1Mb of data was transmitted in a number of packets, with a smaller packet size resulting in a larger number of packets, which creates more granular data)
    4748* Began connecting to a Spectrum Analyzer

    4950=== Week 5
    5051* Figured out how to see a signal on the spectrum analyzer by increasing the gain
    5152* Researched and practiced effectively using the Spectrum Analyzer and how to save and move files onto a personal computer
    5253* Conducted 49 tests to see the effects of varying gain and sampling rate on different modulations
    53 * Began analyzing the spectrum analyzer's output in MATLab to find the total leakage in each waveform and plotting it vs the sampling rate for each modulation at various gains ^([#hn Image 5])^ (defining the intended bandwidth to be within the -3dB bandwidth of the waveform from the peak of the signal to the peak of the noise floor)
     54* Began analyzing the spectrum analyzer's output in MATLab to find the total leakage in each waveform and plotting it vs the sampling rate for each modulation at various gains (defining the intended bandwidth to be within the -3dB bandwidth of the waveform from the peak of the signal to the peak of the noise floor)
