The Multichannel Frame

A multichannel frame contains more than one channel, as specified by the
window size and window offset. A complete multichannel frame consists
of 1 – 1024 channels, starting with channel 0. The particular channels of
the multichannel frame that are selected for the SPORT are a combination
of the window offset, the window size, and the multichannel select regis-
ters. See Figure
