1. Analyzed results of ADC testing
2. Added to presentation for lab meeting
----------------------------------------------------------
1. Wrote Matlab code to find standard deviation, variance, and mean of collected data sets and plot the data.
2. Added more slides to my presentation for the lab meeting. Covered testing setup and purpose of high quality ADCs for a robot.

1. Acquired test data at 2.5 MHz with different function generator.
2. Measured voltage across input resistors for analog and digital voltage supplied to board. Allows calculation of power consumption.

1. Completed ADC frequency testing
-------------------------------------------------------------------
1. Acquired remaining test data using the function generator. Tested multiple data rates ranging from 60 sps to 4800 sps with input signal frequencies ranging from 20 Hz to 100 kHz. Also did a few tests to see the effects of adjusting the programmable gain, turning on the input buffers, and utilizing the unipolar mode.
