WebA low-pass filter is used to remove unwanted high frequency “noise” on a signal. In DAQ systems, analog filters were used to attenuate signal content higher or lower than a certain frequency, to reduce “noise” in the signal. These filters were normally part of the DAQ system’s signal conditioners or preamplifiers. WebThe process of varying an RF carrier wave as per the information in a low-frequency signal is known as modulation. Modulation is the method that superimposes low-frequency signals over high-frequency carrier signals. Demodulation is the process of extracting the primary information-carrying signal from a modulated carrier wave.
