We had previously proposed a wideband phase measurement system based on the three-voltmeter method using a normal thermal voltage converter (TVC) for measuring the differential ac voltage between two ac voltage signals. Several problems were recorded

IEEE Transactions on Instrumentation and Measurement. 68:2021-2026
This paper describes a new phase difference measurement system based on the three-voltmeter method (3VM) by introducing differential ac/single-ended dc switching for a thermal voltage converter (TVC). The 3VM-based phase difference measurement system

Slow diaphragmatic breathing is one of the therapeutic methods used in behavioral therapy for panic disorder. In practice, we have noticed that some of these patients could not perform diaphragmatic breathing and their percent vital capacity was init

This paper proposes a novel method that uses two phase-locked signal generators to evaluate wideband voltage dividers that have wide voltage ratio ranges, including atypical ratios like 1/101. These voltage dividers are intended to be fabricated by a

For expanding the impedance and frequency ranges of a calibration system for ac shunt resistors, a current bridge method with cascaded current transformers (CTs) has been developed. An ac shunt resistor with a nominal value of 10 $\text{m}\Omega $ is

SUMMARY The improved current-bridge method and its mathematical mode are proposed for accurate low-impedance measurement. To realize the accurate measurements of shunt resistors smaller than 1 mΩ, the expansion of current ratio of a current transfor
