Group: Mechanical filters.
Nor was the method first discovered in the field of mechanical filters;
Mechanical filters in other languages.
Ceramic cleaning devices are used simultaneously with mechanical filters.
The first volume production of mechanical filters was undertaken by Collins Radio Company starting in the 1950s.
The method of coupling between non-adjacent resonators is not limited to mechanical filters.
Despite the fact that the internal mechanical filters have a low potential, they are in demand, and demand is quite justified.
Both magnetostrictive andpiezoelectric transducers are used in mechanical filters.
The theory of mechanical filters was first applied to improving the mechanical parts of phonographs in the 1920s.
Frequencies of the order of megahertz(MHz)are above the usual range for mechanical filters.
Mechanical filters, in turn, do not let the particle sizes for flow-through dangerous parts of the pump and the formative elements fountain.
Another common piezoelectric material is quartz,which has also been used in mechanical filters.
Air cleaners that remove particles include high-efficiency mechanical filters and electronic air cleaners, such as electrostatic precipitators.
This makes it possible to apply electrical network analysis andfilter design methods to mechanical filters.
Air cleaners that remove particles include high-efficiency mechanical filters and electronic air cleaners, such as electrostatic precipitators.
Chemical filters are used to remove things that are dissolved in the water, andtherefore cannot be removed by mechanical filters.
The frequency response behaviour of all mechanical filters can be expressed as an equivalent electrical circuit using the impedance analogy described above.
A representative selection of the wide variety of component forms and topologies for mechanical filters are presented in this article.
The frequency response behaviour of all mechanical filters can be expressed as an equivalent electrical circuit using the impedance analogy described above.
Under-gravel filters, though primarily used for biological filters, also act as mechanical filters by trapping debris in the gravel.
Mechanical filters quickly also found popularity in VHF/UHF radio intermediate frequency(IF) stages of the high end radio sets(military, marine, amateur radio and the like) manufactured by Collins.
The frequency at which the transition from lumped to distributed models takes place is much lower for mechanical filters than it is for their electrical counterparts.
Overall, mechanical filters with lumped elements of all kinds can cover frequencies from about 5 to 700 kHz although mechanical filters down as low as a few kilohertz(kHz) are rare.
This has givenway to nickel-iron alloys, primarily to maximise the Q since this is often the primary appeal of mechanical filters rather than price.
Nor was the method first discovered in the field of mechanical filters; the earliest description is in a 1948 patent for filters using microwave cavity resonators.
However, mechanical filter designers were the first(1960s) to develop practical filters of this kind and the method became a particular feature of mechanical filters.
The ion-chargers in these types of filters produce ozone byproduct, more than fans in mechanical filters but may still be within the acceptable level.
This could be applied to problems that were entirely in the mechanical domain, but for mechanical filters with an electrical application it is necessary to include the transducer in the analogy as well.
The high"quality factor", Q, that mechanical resonators can attain, far higher than that of an all-electrical LC circuit,made possible the construction of mechanical filters with excellent selectivity.
