| Band Pass Filter circuit (a) |  |
| Band Pass Filter circuit (b) |  |
| Shape of (a) and (b) are not ideal as circuit is only an approximation | |
| Band Pass Filter circuit (c) |  |
| Band Pass Filter circuit (d) |  |
| In (c) and (d) filters are cascaded to give better response | |
| Band Pass Frequency Response |  |
| Band Stop Filter circuits |  |
| Band Stop Frequency Response |  |
| LC tuned circuits can be used for either | |
