Appraisal of a low noise electrocardiogram
Journal of the American College of Cardiology, 1983 Two low noise electrocardiographic systems were designed to record low amplitude His-Purkinje potentials in the PR segment and delayed depolarization potentials in the ST-T segment from the body surface on a beat to beat basis. In one system, a bipolar electrode was utilized and the noise level was optimally reduced to 2 to 2.5 microV by a combination ...

Noise-optimized ultrastable low-noise current amplifier [PDF]
Review of Scientific Instruments, 2019 We have developed a noise-optimized ultrastable low-noise current amplifier (ULCA) aimed at reducing the uncertainty at low currents. It involves a thin-film resistor network with 6.75 GΩ at the high-ohmic path which reduces the noise level to 1.6 fA/Hz. Noise investigations as well as short-term and long-term stability studies were carried out.

Low-discrepancy blue noise sampling [PDF]
ACM Transactions on Graphics, 2016 We present a novel technique that produces two-dimensional low-discrepancy (LD) blue noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we construct two-dimensional LD point sets, and rearrange them to match a target spectral profile while preserving their low discrepancy.
