The output connection method.

Notes¶

• "sum": The output of each polyphase partition is summed to produce the output signal \(y[n]\) (used in decimation).

• "top-to-bottom": The output of each polyphase partition is commutated from top to bottom (used in interpolation).

• "bottom-to-top": The output of each polyphase partition is commutated from bottom to top.

• "all": The outputs of each polyphase partition are used in parallel (used in channelization).
