Filters of some sort are highly essential for operating of most electronic based circuits. However, it shows its necessity in computer, mechanical and so on fields too. After days going on, active and passive filters are using gradually escalate. Basically, active means make a filter by using amplifier, transistor and so on which is used for improving the predictability as well as performance of a filter. On the other hand, passive filter actually makes by four basic linear elements such as resistor, capacitor, transformers and inductor. However, non linear passive filters are more complex such as transmission lines. Higher order filters provided greater roll off rates between pass band and stop band. They are also necessary to achieve required levels of attenuation or sharpness of cutoff. In this paper will be discussed High Pass Filter (HPF) and Low Pass Filter (LPF) in both active and passive cases with simulated wave shapes. Furthermore, Here will be simulated the high order low pass and high order high pass filters as well for showing the importance of high order.
