| Product Description |
A band-pass filter is a device that allows waves in a specific frequency band to pass while shielding other frequency bands. It refers to a filter that can pass frequency components in a certain frequency range, but attenuate frequency components in other ranges to an extremely low level Device.
In fact, there is no ideal bandpass filter. The filter cannot completely attenuate all frequencies outside the desired frequency range, especially there is a range that is attenuated but not isolated outside the desired passband. This is usually called the roll-off phenomenon of the filter, and is expressed in dB per decade of attenuation amplitude. Generally, the filter design should ensure that the roll-off range is as narrow as possible, so that the performance of the filter is closer to the design.
