This is a screenshot of the current datalogger GUI.

The datalogger hardware is a slightly modified version of datalogger shield mounted on a Tiva LaunchPad development board. Inputs were generated using a second Tiva LaunchPad outputting analog (pwm) signals of the form A = a*sin(bt)*sin(ct) and B = d*sin(bt)*cos(ft). Analog signals were passed through a passive, first-order low pass filter before being read. Red data were read on channel A, blue on channel B. While outputs from the signal generator were similar in voltage, the channel A data (red) appears much more intense due to its being amplified 12 dB relative to the channel B data (blue).
