To create a passive low-pass filter, we need to combine a resistive element with a reactive element. In other words, we need a circuit that consists of a resistor and either a capacitor or an inductor. In theory, the resistor-inductor (RL) low-pass topology is equivalent, in terms of filtering ability, to the resistor ...

WebLow-pass filter: A ‘low-pass filter’, also referred to as a ‘high-cut filter’, allows only frequencies that are lower than a certain point to pass through. Simultaneously, it filters out the frequencies that are higher than that point. Pass filters have two controls. They are the filter’s cut-off frequency and the filter’s slope. WebThus, the Active Low Pass Filter has a constant gain A F from 0Hz to the high frequency cut-off point, ƒ C.At ƒ C the gain is 0.707A F, and after ƒ C it decreases at a constant rate as the frequency increases. That is, when the frequency is increased tenfold (one decade), the voltage gain is divided by 10. In other words, the gain decreases 20dB (= 20*log(10)) … high gloss black watch
