Abstract
A device for selecting a channel comprises a speed detector configured to detect a speed of a channel selecting mechanism; a controller connected to the speed detector; and a frequency deviation detector connected to the controller and is configured to receive an input signal. The controller selects a wideband channel searching mode for the frequency deviation detector if the speed is higher than a speed threshold, or a narrowband channel searching mode if the speed is lower than the speed threshold. The frequency deviation detector detects an existence of a channel when either an actual frequency deviation of the input signal is lower than a first wideband frequency deviation threshold when the wideband channel searching mode is selected, or the actual frequency deviation is lower than a narrowband frequency deviation threshold when the narrowband channel searching mode is selected.
