Ultra low noise current sources
IEEE Instrumentation and Measurement Technology Conference Sensing, Processing, Networking. IMTC Proceedings, 1998The current sources which are normally used in research laboratories are not suitable for low noise measurement systems because of the unacceptable level of low frequency noise which they introduce in the measurement chain. The most important source of low frequency noise in such instruments is the solid state device (usually a Zener diode) which is ...

The author describes a set of design rules which are general and can be used to produce oscillators with a very low noise performance where both additive and flicker noise are considered. Linear theories which accurately describe the noise performance of resonator-type oscillators are presented.

A burster for separating successive sheets of paper from a continuous web of paper has at least one output or draw roller having a larger diameter than the input or feed rollers with all of these rollers rotated at the same r.p.m. and a simple belt drive mounted on a pivotal double link with a one-to-one ratio provides for driving one set of rollers ...

An axial flow fan includes blades mounted on a hub and extending radially outward to a shroud disposed around the hub. Pairs of stators are connected to the shroud at positions angularly spaced about the inner periphery of the shroud. Each pair of stators includes a trailing stator angularly spaced from a leading stator by a distance related to the ...

A practical method of computation is described for making periodic signals V(t) which have a given frequency spectrum and which minimize the variance 〈(V2−〈V〉2)2〉 in power as a function of time. These signals can be used to measure the spectral response of a system (the transfer function): They represent a significant improvement over traditional ...

Much of the recent progress in our understanding of the world around us was achieved through the ability to detect very weak signals, for example from outer space, from nerve fibers, or from the ocean floor. To detect these weak signals, one requires very sensitive receivers, and hence the ability to amplify these signals without, at the same time ...
