Hi
I want to design a circuit to amplify low frequency and weak signal,so I need a LPF that corner frequency is 5kHz .I need to know which kind of filter is more suitable,active filter or LC filter? Is it right to choose Butterworth filter and then select the capacitance and resistance? How to choose the order of filter , isn't it better to be higher?
Or is there something wrong my idea ? What should i consider on the design of filter?
Thanks
