Embodiment Construction
[0022] Aspects and examples of the invention will now be described. The following description provides specific details for a thorough understanding and illustration of these examples. However, it will be understood by those skilled in the art that the present invention may be practiced without these details. Also, some well-known structures or functions may not be shown or described in detail to avoid unnecessarily obscuring the related description.
[0023] figure 1 A block diagram of a channel selection device in an embodiment is shown. The channel selection device 10 includes a speed detector 110 , a controller 120 and a frequency deviation detector 130 . The speed detector 110 is configured to detect the speed of a channel selection component, such as a turning wheel. Accordingly, for example, the speed of the channel selection wheel may comprise a rotational speed. In one example, the channel selection device 10 is incorporated in an AM radio (amplitude modulation r...

The invention relates to the communication field, and discloses a channel selection device and a method thereof. The device in the present invention includes: a speed detector configured to detect the speed of the channel selection component; a controller connected to the speed detector; a frequency deviation detector connected to the controller and configured to receive an input signal. When the speed is higher than the speed threshold, the controller is configured to select the wideband channel search mode, or when the speed is lower than the speed threshold, select the narrowband channel search mode; when the wideband channel search mode is selected, if the actual frequency of the input signal The frequency offset detector is configured to detect an existing channel if the deviation is below the first wideband frequency deviation threshold, or when the narrowband channel search mode is selected, if the actual frequency deviation of the input signal is below the narrowband frequency deviation threshold. Channels can be accurately searched without missing channels, thereby improving the user's channel search experience.
Description
technical field [0001] The present invention relates to the communication field, in particular but not limited to a channel selection device and method thereof. Background technique [0002] Traditional AM radios usually implement channel searching by utilizing a microprogrammed control unit (MCU) to detect frequency deviation. However, the conventional channel search device cannot match the speed of the channel search part, and it is easy to miss the target channel. Therefore, there is an urgent need for an AM radio that can improve channel search capabilities and reduce missed target channels. Contents of the invention [0003] The purpose of the present invention is to provide a channel selection device and its method, which can automatically track the speed detection channel of the channel selection unit, and accurately search channels without missing channels. [0004] According to an embodiment of the present invention, a channel selection device includes: a speed ...
