What is the behavior of the waveform when Input 1 is -100uV and Input 2 is -50uV?

When analyzing the behavior of the waveform based on the given voltage inputs of -100uV for Input 1 and -50uV for Input 2, it’s important to understand how differential voltages work in EEG readings. Specifically, the EEG waveform represents the difference between the two input voltages.

In this case, Input 1 is more negative than Input 2. The calculation for the difference would be Input 1 minus Input 2, which translates to -100uV - (-50uV), equating to -50uV. Since the resultant difference is negative, the waveform would reflect this as a deflection downward.

The upward deflection typically signifies an increase in voltage towards the positive end, and staying neutral would suggest that both inputs are the same. A chaotic waveform would imply erratic and inconsistent signals, which is not indicated in this scenario with defined and stable values. Hence, the behavior of the waveform is correctly described as deflecting downward due to the more negative input value, leading to the conclusion that this choice reflects the situation accurately.
