Abstract
A signal processing method includes the steps of: receiving, by a first measurement circuit, an analog measurement signal from a device under test; digitizing, by the first measurement circuit, the analog measurement signal, thereby obtaining a digital measurement signal; removing, by a first noise reduction circuit, noise from the digital measurement signal, thereby obtaining a noise-corrected measurement signal; receiving, by a second measurement circuit, an analog reference signal, wherein the device under test generates the analog measurement signal based on the analog reference signal; digitizing, by the second measurement circuit, the analog reference signal, thereby obtaining a digital reference signal; removing, by a second noise reduction circuit, noise from the digital reference signal, thereby obtaining a noise-corrected reference signal; and determining, by a subtraction circuit, a digital difference signal based on the noise-corrected measurement signal and based on the noise-corrected reference signal. Further, a measurement system is described.
