If G1 = 60 μV and G2 = 10 μV, what is the output signal voltage?

To determine the output signal voltage when given G1 (60 μV) and G2 (10 μV), it’s important to understand how these values interact in the context of the problem, possibly indicating the use of summation and subtraction based on their respective signs.

If G1 and G2 represent two independent signals, with G1 being a positive signal and G2 being a lower positive signal, it follows that you would sum their values. However, if one of the signals is inverted or operates under a condition that affects its polarity, then the calculation would shift.

In this case, if G2 is considered a negative signal contributing to the output when compared to G1, the output would be calculated as follows:

Output Voltage = G1 - G2 = 60 μV - 10 μV = 50 μV.

Thus, this result reflects the interference between the two signals. An output of 50 μV indicates the net positive signal strength after accounting for the contribution of both signals, highlighting a common calculation method used in data outputs in sleep physics or related fields.
