转换器, 频率变换器
a device used to alter the frequency of a radio signal
A converter is a device that changes the frequency of a radio signal to make it compatible with the equipment receiving it. It works by taking signals that are transmitted at one frequency and converting them to a different frequency that can be processed by the radio or other devices. This allows the receiver to capture and interpret signals that would otherwise be out of its frequency range, enabling the reception of various radio channels or other types of communication.
