This 1st-Order low pass type filter, consists simply of a passive RC filter connected to the input of an inverting operational amplifier. Filter is basically linear circuit that helps to remove unwanted components such as Noise, Interference and Distortion from the input signal. Ideally Filter alters the relative amplitudes of the various frequency components and the phase characteristics and its 'Gain' depends entirely on the signal frequency.

Input - Capacitor - (Output) - Resistor - Ground. High pass filters filter out signal with frequencies below the cutoff frequency (1/2πRC). Since the cutoff is strictly determined by R and C, choose the appropriate resistor and capacitor to cutoff frequencies where you want to. The output signal is phase shifted from the input.The use of polypropylene depth filters or high-flow pleated filters on the deionization system is used to treats incoming water and protects the RO system. Trap filters ensure that the make-up process water is ultra-pure by preventing downstream contamination of source water sediment or ion exchange bead migration. High-Purity SolventsBand stop filters are generally classified as: Wide band stop filter; Narrow band stop filters; The narrow band-reject filters are sometimes referred to as notch filters due to the fact that these possess high-value quality factor i.e., Q more than 10 where the bandwidth is very small in comparison to wide band reject filters.The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage. The filter circuit can be constructed by the combination of components like capacitors, resistors, and inductors. Electronic filters are four-terminal devices that serve to transfer electrical current between the source and load in a certain frequency range. The transparency range of the filter is the frequency range where the filter conducts without losses. The attenuation range of the filter is the frequency range where the filter conducts with attenuation.Transfer Functions.
