While not new, techniques to eliminate amplifier instability and other undesirable effects such as cross modulation are often misused. For example, you might assume that when choosing a decoupling capacitor for amplifiers, the degree of decoupling will be greater the larger the capacitance of the capacitor.
This is generally true, but it does not take into account that large capacitors have significant parasitic series inductance, which does not effectively shunt high frequencies. To obtain the desired shunting of both high and low frequencies, a chain of two or more capacitors connected in parallel should be created - a large capacitor for low frequencies, and a small capacitor for high frequencies.

Traffic noise delays the growth of chicks
06.05.2024
The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals
05.05.2024
The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>
| Random news from the Archive New Salt Formula
15.04.2021
The American company MicroSalt has created an improved salt formula, which contains 50% less sodium. The product is positioned as more beneficial to health
The developer describes his product as "particles coated with nanosized salt crystals." The carrier (usually maltodextrin) acts as a transport molecule to deliver small salt crystals. These crystals are naturally attached to the carrier using electrostatic forces. The salt dissolves almost immediately due to the extremely small size of the crystals.
The updated salt formula is about 100 times smaller than the traditional salt formula and requires less to achieve the same level of flavor.
The company claims that the new product has the same level of salinity compared to the traditional one, it contains 50% less sodium. In the future - to increase this figure to 80%.
The company has already patented its technology and started collecting investments through crowdfunding.
