Signal Quantization Analysis in MATLAB

GOAL: use MATLAB quantize simulated data

SKILLS: MATLAB programming

I wrote a MATLAB program to examine the impact of signal quantization for computing the derivative of a signal.

In this scenario, I want to use a potentiometer for sensing a joint angle that can be powered with either system at 5.0 volts or 3.3 volts. Using MATLAB, I simulates a test signal as a sine wave of 0.15 volt amplitude at 1 Hz and quantize it based on the limitations of an Arduino Uno versus Zero.
