WebFeb 1, 2024 · The Swedish subsidiary of ITT, Standard Radio & Telefon, built a couple nice SW receivers using mechanical filters from one of the RFT-Werke. Hopefully, that was the closest someone or something from the DDR got to get into the Very Special locations those were used, as the military and the SIGINT agency were one of the major users. WebSep 16, 2011 · A crystal can be used as an electromechanical filter for example. For a purely mechanical filter, attach a large mass to an object. The mass acts as a capacitance and can be analyzed in the same way as an electrical system. If you'd like more information about this, look up "spring mass damper" systems.

Mechanical filters in electronics

WebA crystal filter allows some frequencies to 'pass' through an electrical circuit while attenuating undesired frequencies. An electronic filter can use quartz crystals as resonator components of a filter circuit. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits ( see mechanical filter ).

WebMechanical filters must be replaced at least three times per year and this means a big economic expenditure. The range of FE SYSTEM electronic filters generates a saving on energy costs equal to 30%. Reliability and performance of Expansion Electronic filters ensure low operating costs throughout the entire life of the plant. Passive implementations of linear filters are based on combinations of resistors (R), inductors (L) and capacitors (C). These types are collectively known as passive filters, because they do not depend upon an external power supply and they do not contain active components such as transistors. Inductors block high-frequency signals and conduct low-frequency signals, whi…
