Self-Noise Reduction for Capacitive Sensors via Photoelectric DC Servo: Application to Condenser Microphones
Hirotaka Obo, Atsushi Tsuchiya, Tadashi Ebihara +1
The self-noise of capacitive sensors, primarily caused by thermal noise from the gate-bias resistor in the preamplifier, imposes a fundamental limit on measurement sensitivity. In…

Noise Suppression for Time Difference of Arrival: Performance Evaluation of a Generalized Cross-Correlation Method Using Mean Signal and Inverse Filter
Hirotaka Obo, Yuki Fujita, Masahisa Ishii +4
This paper proposes a novel generalized cross-correlation (GCC) method, termed GCC-MSIF, to improve time difference of arrival (TDOA) estimation accuracy in noisy environments. Con…
