Abstract
A band pass filter includes partial filters, each of which has a pass band. Pass bands of different ones of the partial filters have center frequencies that are different. A partial filter with a lowest center frequency has a pass band with a first low-frequency edge and a first high-frequency edge. The first low-frequency edge is steeper than first high-frequency edge. A partial filter with a highest center frequency has a pass band with a second low-frequency edge and a second high-frequency edge. The second high-frequency edge is steeper than the second low-frequency edge.
