FM broadcast
(hybrid analog/digital with standard partition)

This is an example of a hybrid analog/digital FM broadcast signal employing the iBIQUITY FM transmission specification. Lower and upper digital OFDM sidebands are present. According to the specification, each main digital sideband is 69.041 kHz wide (not including the two shoulders), and transmits 10 frequency partitions each. The specification allows for 1, 2, or 4 additional partitions in each sideband to increase digital capacity at the expense of analog signal quality.
