Abstract
The determination and identification of channels in a signal is an important aspect of the operation of a signal receiver. A method () is described including the steps receiving () a signal containing a plurality of channels, filtering () the signal to produce an indicator of a channel band edge, and determining () a characteristic of the channel based on the indicator. Additionally, an apparatus () is described including a spectrum shift circuit () that receives an input signal and shifts the frequency spectrum of the signal, a filter () that filters the frequency shifted signal to produce an indicator of a band edge of a channel, and a signal analysis circuit () that determines a characteristic of the channel based on the indicator of the band edge, the signal analysis circuit () controlling the frequency shift in the spectrum shift circuit () based on the determined characteristic of the channel.
