1 which of the circuits if any could be a band pass filter 2

1. which of the circuits (if any) could be a band pass filter?
2. which of the circuits (if any) could be a high-pass filter?
3. which of the circuits (if any) could be used to achieve a butterworth characteristic?
4. which of the circuits (if any) could be a band rejection filter?
5. which of the circuits (if any) could be a low-pass filter?

Solution

1) II

FOR LOW FREQUENCIES CAPACITANCE OFFERS HIGH RESISTANCE AND

FOR HIGH FREQUENCIES INDUCTANCE OFFERS HIGH RESISTANCE

SO THE SERIES CONNECTION OF CAPACITANCE AND INUCTANCE ACTS AS A BAND PASS FILTER

2) NO CIRCUIT

3) I

DUE TO THE PRESENCE OF INDUCTANCE IT GIVES THE CHARACTERISTICS OF BUTTERWORTH LOW PASS FILTER

4) III

FOR LOW FREQUENCIES CAPACITANCE OFFERS HIGH RESISTANCE AND

FOR HIGH FREQUENCIES INDUCTANCE OFFERS HIGH RESISTANCE

SO THE PARALLEL CONNECTION OF CAPACITANCE AND INUCTANCE ACTS AS A BAND REJECTION FILTER

5) I

FOR HIGH FREQUENCIES INDUCTANCE OFFERS HIGH RESISTANCE AND OFFERS ;OW RESISTANCE FOR LOW FREQUENCIES. SO DUE TO THE PRESENCE OF INDUCTANCE IT ACTS AS A LOW PASS FILTER

1. which of the circuits (if any) could be a band pass filter? 2. which of the circuits (if any) could be a high-pass filter? 3. which of the circuits (if any)
