All signals above selected frequencies get attenuated. They are of two types-Active Low Pass FilterandPassive Low Pass Filter. The frequency response of the low pass filter is shown below. Here, the dotted graph is the ideal low pass filter graph and a clean graph is the actual respo...
This circuit connects or “cascades” two passive first-order low-pass filters to form a second-order filter network. Therefore, we can make that simply by adding another first-order low-pass filter to an additional RC network. When the n number of this type of RC step is cascaded, the ...

Bilinear lowpass–lowpass transformation (BLLTIn this paper, a new passive complex filter is proposed. In the same fashion as the traditional real band-pass filter, the proposed circuit is also designed through the frequency transformation. In order to obtain the prototype complex filter suitable ...
An innovative theory on the passive circuits capable to generate low-pass negative group delay (NGD) behaviour is introduced. An identification method enabling to identify the first-order NGD simple cells built with resistor-inductor (RL)- and resistor-capacitor (RC)-networks is elaborated. The fu...
