Background Muscle damage leads to increased serum creatine kinase (CK) levels in
diseases such as acute myocardial infarction. Still, many individuals have abnormal serum …

The magnetic anomaly signal tends to be contaminated by ambient environmental noise
due to the complexity and diversity in the field of magnetic anomaly detection (MAD). The …

Aiming to overcome the problem of the frequency error between the reference signal and the
measured signal in an analog lock-in amplifier, this paper presented a digital lock-in …

The magnetic anomalies generated by the ferromagnetic targets are usually buried within
uncontrollable interference sources, such as the power frequency and random noises. In …

The accuracy of time delay estimation seriously affects the accuracy of sound source
localization. In order to improve the accuracy of time delay estimation under the condition of …

The free induction decay (FID) signal output by a proton precession magnetometer (PPM) is
usually only of the microvolt level, and its frequency is proportional to the magnetic field …

Magnetic sensing platform techniques have been used in many years in an attempt to better
evaluate the likelihood of recoverable hydrocarbon reservoirs by determining the depth and …

In the field of magnetic anomaly detection (MAD), the anomaly signal is easily submerged by
ambient electromagnetic interference. Though the existing noise suppression methods can …

The frequency of a free induction decay (FID) signal from an industrial proton precession
magnetometer (PPM) is proportional to the magnetic field strength. To achieve high …

Nuclear magnetic resonance (NMR) spectroscopy is commonly used to characterize
molecular complexity because it produces informative atomic-resolution data on the …
