Static (solid state) frequency converters convert AC electrical power of one frequency into AC electrical power of another frequency. To realize high efficiency, great manageability and energy saving in industrial induction motor related applications, it is necessary to adopt controllable frequency converter systems.

In the 1950’s and 1960’s sodium phosphate was used often in household detergents to increase cleaning power. This added phosphates to the water supply and therefore dramatically increased phosphate levels in some lakes and streams. This unnatural rise in phosphate levels increased algae growth dramatically, causing many problems for …

By definition, a low-pass filter is a circuit offering easy passage to low-frequency signals and difficult passage to high-frequency signals. There are two basic kinds of circuits capable of accomplishing this objective, and many variations of each one: The inductive low-pass filter in Figure below and the capacitive low-pass filter in Figure below

Debris causes both filter clogging solids and algae growing phosphates, both of which make pool maintenance much harder. Removing debris early and often makes maintenance much easier. Of course, if you don't have an automatic cleaner, you'll need to vacuum the bottom maybe twice a week, and certainly immediately after strong winds.

In power supplies, band-reject filters are used to suppress a 50- to 60-Hz line frequency. 1.1 System Description Filters can be classified as passive or active.

Filter Media: Carbon is a good filter media, but it can add phosphate to the water column so choose carefully. Some carbon media, such as those for saltwater aquariums, is formulated specifically to not leach phosphates into the water. Others combine carbon media with phosphate absorbers so you get the best of both.

The amount of attenuation for each frequency depends on the filter design. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter. High-pass filters have many uses, such as blocking DC from circuitry sensitive to non-zero average voltages or radio frequency devices.

An optical filter with the same function can correctly be called a low-pass filter, but conventionally is called a longpass filter (low frequency is long wavelength), to avoid confusion. In an electronic low-pass RC filter for voltage signals, high frequencies in the input signal are attenuated, but the filter has little attenuation below the cutoff …
