Band Pass Filter

It passes frequency with in the certain range.Circuits can be designed to accomplish this task by combining the properties of low-pass and high-pass into a single filter. The result is a band-pass filter.

Types:

1. Capacitive band-pass filter.


This construction allows the frequency that are neither too high nor too low.The response of a capacitive bandpass filter peaks within a narrow frequency range.

2.Inductive band-pass filter.

Band-pass filters can also be constructed using inductors. But, the capacitive band pass filter gives more advantage.

Here, the high-pass section comes “first” in this design instead of the low-pass section makes no difference in its overall operation. It will still filter out all frequencies too high or too low.


  • A band-pass filter works to screen out frequencies that are too low or too high, giving easy passage only to frequencies within a certain range.
  • Band-pass filters are built by stacking a low-pass filter on the end of a high-pass filter, or vice versa.
