JLHS: A Joint Linear Frequency Modulation and Hyperbolic Frequency Modulation Approach for Speed Measurement

IEEE Access, 2020
In the waveform design, the distance measurement and resolution are a pair of irreconcilable contradictions. Linear Frequency Modulation (LFM) can alleviate this contradiction.

Transmission Perspective on the Mechanism of Coarse and Fine Crackle Sounds

Archives of Acoustics, 2021
The possibility of a normal distribution indicates that few particles are in the same phase during a breath and their reflections can be observed on the chest wall, then a few explosive waves with relatively large power occurr occasionally.

Maximizing precision over extended unambiguous range for TOF range imaging systems [PDF]

, 2010
The maximum unambiguous range for time-of-flight range imaging systems is inversely proportional to the chosen modulation frequency. However, increasing the unambiguous range by decreasing the modulation frequency will generally also degrade the range ...

Method of calibrating modulation meter MI 2305

Vojnotehnički Glasnik, 2000
In this article an original way of calibrating the MI 2305 modulation meter is described. AM traceability is achieved using tree secondary etalons. FM traceability calibrating is achieved by using the Bessel zero method.

Suppression of Frequency Modulation to Amplitude Modulation Conversion with Modified Group Velocity Dispersion Compensation Device in the Front End of High-Power Lasers

Applied Sciences, 2022
The group velocity dispersion (GVD) occurring in the front end of high-power lasers is one of the primary factors leading to the conversion of frequency modulation (FM) to amplitude modulation (AM).

Comparative Analysis of Super-Kamiokande and SNO Solar-Neutrino Data and the Photospheric Magnetic Field [PDF]

, 2006
We analyze Super-Kamiokande, SNO, and photospheric magnetic-field data for the common time interval, namely the SNO D2O phase. Concerning rotational modulation, the magnetic-field power spectrum shows the strongest peaks at the second and sixth harmonics
