A pass filter also affects all energy above or below the target frequency, often referred to as the cutoff frequency in a pass filter. However, instead of boosting or cutting that content by a specific amount of gain, it instead removes that frequency content completely. Any frequency content outside the cutoff frequency is attenuated or cut gradually in a downward slope, heading towards negative infinity.
