Unfortunately, measuring analog signals with a data acquisition device is not always as simple as wiring the signal source leads to the data acquisition device. Among the most common types of noise are electronic noise, thermal noise, intermodulation noise, cross-talk, impulse noise, shot noise and transit-time noise. For systems with multiple circuits, it is important to isolate the noisy devices to ensure that the signal wiring does not create a ground loop by providing a return path between the ground planes. Consequently, the noise-induced simplification . The higher the noise level, the faster the hearing loss. Induced noise is the noise generated in a circuit by a varying magnetic or electrostatic field produced by another circuit.
