Compensation of impedance meters, when using an external front-end amplifier
Four-terminal impedance meters based on pseudo-bridges yield unexpected uncertainties when using high-contact-impedance electrodes. Adding a front-end amplifier to the impedance meter and rearranging the connection of the meter terminals overcome the contact impedance problem. However, because the compensation provisions in the instrument are meant to compensate only impedance residuals of test...
متن کاملTunable selective receiver front end with impedance transformation filtering
A highly selective impedance transformation filtering technique suitable for tunable selective RF receivers is proposed in this paper. To achieve blocker rejection comparable to SAW filters, we use a two stage architecture based on a low noise trans-conductance amplifier (LNTA). The filter rejection is captured by a linear periodically varying (LPV) model that includes band limitation by the LN...
متن کاملFront-End Compensation Methods for LVCSR Under Lombard Effect
This study analyzes the impact of noisy background variations and Lombard effect (LE) on large vocabulary continuous speech recognition (LVCSR). Robustness of several front-end feature extraction strategies combined with state-of-the-art feature distribution normalizations is tested on neutral and Lombard speech from the UT-Scope database presented in two types of background noise at various le...
متن کاملBroadband beamforming compensation algorithm in CI front-end acquisition
BACKGROUND To increase the signal to noise ratio (SNR) and to suppress directional noise in front-end signal acquisition, microphone array technologies are being applied in the cochlear implant (CI). Due to size constraints, the dual microphone-based system is most suitable for actual application. However, direct application of the array technology will result in the low frequency roll-off prob...
متن کاملAn Unconditionally Stable Front End
This paper presents the design and simulation of a 2.4 GHz ISM band front end single stage Low Noise Amplifier (LNA) for wireless transceiver system. This amplifier uses AVAGO ATF-54143 transistor which is a low noise and high dynamic range Pseudomorphic high electron mobility transistor. The proposed method is addressed to optimize noise performance and power efficient while maintaining good i...
