What are the advantages of filtering the signal?
The main reason to filter a signal is to reduce and smooth out high-frequency noise associated with a measurement such as flow, pressure, level or temperature. A common example is the noise associated with the differential pressure (DP) across an orifice plate used to infer flow rate.
What is the purpose of using filter?
Filters are systems or elements used to remove substances such as dust or dirt, or electronic signals, etc., as they pass through filtering media or devices. Filters are available for filtering air or gases, fluids, as well as electrical and optical phenomena.
What is the importance of filters in communication circuits?
Radio communications: Filters enable radio receivers to only "see" the desired signal while rejecting all other signals (assuming that the other signals have different frequency content). DC power supplies: Filters are used to eliminate undesired high frequencies (i.e., noise) that are present on AC input lines.
What are 3 advantages of digital filters?
Digital filters require only the arithmetic operations of addition, subtraction, and multiplication. Digital filters do not drift with temperature or humidity or require precision components. Digital filters have a superior performance-to-cost ratio. Digital filters do not suffer from manufacturing variations or aging.
