A blower for fluidized particulates has a housing with an inlet in one wall. The housing defines a chamber which also has an outlet. A rotatably mounted shaft projects into the interior of the chamber. Circumferentially spaced around and projecting laterally from the shaft are a plurality of blades which individually have a shape selected to ...

Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.

Any analysis of single-channel current events needs sufficient resolution of the signals from the background noise, which is accomplished by reasonable low-pass filtering. An increase of the recording bandwidth is therefore possible only if the background noise in the recording system is reduced.

Low noise avalanche photodiodes
Journal of Lightwave Technology, 2004Avalanche photodiodes (APDs) are used in many applications when conventional unit y gain photodiodes cannot provide enough sensitivity and the extra amplification provided by the impact ionization process gives it an advantage. Unfortunately this amplification or gain of the incoming optical signal is always accompanied by some 'excess noise' due to ...

The design specification of electronic equipment dealing with low-level signals should include limits on noise, signal-to-noise ratio, or on the functional reliability or error rate determined by these quantities. Failure to set noise or noise-detertnined limits, or to design to meet other specifications, leaving the ‘noise problem’ to be sorted out at
