Noise filtering is a set of processes that is performed to remove the noise contained with the data acquired on construction and infrastructure sites. The 3D data obtained need to be processed, and the contained noise should be eliminated or reduced. A noise filter is a device used to remove high-frequency noise. High-frequency noise is generated from the inverter, which is the power conversion device of the equipment, causes a malfunction and communication failure of the source electronic device, peripheral electronic devices, etc.
A wide variety of filters have been proposed to address noise reduction. Broadly speaking, filters can be classified into two categories: Low pass filter: It passes signals with a frequency lower than a certain cut-off frequency and attenuates signals with frequencies higher than the cut-off frequency. You can use linear filtering to remove certain types of noise. Certain filters, such as averaging or Gaussian filters, are appropriate for this purpose. For example, an averaging filter is useful for removing grain noise from a photograph.
Digital Noise Filter in Samsung Smart TV is used to reduce the analog noise that is created during signal transmission. It filters out the disturbance created so that the original images and sharp details can return to the screen.
