filter specifications

Filter specifications describe the performance and characteristics of a filter, such as what frequencies it passes or blocks. Key factors include cutoff frequency, which defines the boundary between the signals a filter allows and those it attenuates; roll-off rate, indicating how quickly the filter transitions between these signals; and insertion loss, representing the signal loss introduced by the filter. Other important specs are bandwidth (range of frequencies passed), insertion loss, and attenuation levels. Together, these specifications ensure the filter effectively isolates desired signals while minimizing interference or noise in electronic or communication systems.
