Differential Measurement

Differential measurement involves comparing two related signals or values simultaneously to determine the difference between them. Rather than measuring each value separately, this method subtracts one measurement from the other, which helps eliminate common noise or interference that affects both signals equally. This approach enhances accuracy and stability, especially in noisy environments. For example, in sensors, differential measurement can improve the detection of small signals by canceling out background disturbances, providing a clearer and more precise reading of the actual difference or change being measured.
