Background
Filtering is an important concept in signal processing, a filter circuit in a direct current stabilized power supply has the function of reducing alternating current components in pulsating direct current voltage as much as possible, keeping the direct current components, reducing the ripple coefficient of output voltage, and smoothing the waveform, so that a filter is called in the device and plays a role, and the filter is a frequency selection device and can enable specific frequency components in signals to pass through and greatly attenuate other frequency components; by using the frequency selection function of the filter, interference noise can be filtered out or spectrum analysis can be carried out. In other words, any device or system that can pass a specific frequency component of a signal and greatly attenuate or suppress other frequency components is called a filter.
The wave filter need carry out the flattening operation before dispatching from the factory, can influence the use and the installation of wave filter if the depth of parallelism on the upper and lower two sides of wave filter is too high, and current flattening device adopts mostly to adopt large-scale instrument and equipment, and the measurement process is complicated to it is costly, can't promote.
