Task No.1 – Compare the performance of active filter and passive filter in terms of load effect (30pts)
1)Using LTspice, realize two circuits below and verify that the both circuits are “low pass filter” using the AC Sweep function (15pts)
1. Active low filter : V(01)의 모양을 보면 H(0)=1, H(infinite)=0이므로 low pass filter의 모양을 갖고 있다. Wc = 1/(Rf*Cf) =1KHZ이다.
2. Passive low filter : V(02)의 모양을 보면 H(0)=1, H(infinite)=0이므로 low pass filter의 모양을 갖고 있다. Wc = 1/(RC) = 1000HZ이다.
