Automatic frequency hopping and channel tracking system for auto-frequency-hopping digital wireless microphone

An automatic frequency hopping and channel tracking system for an auto-frequency-hopping digital wireless microphone, comprising a digital wireless microphone and a digital wireless receiving device;

• the digital wireless microphone including:
• a first digital RF transmitter capable of transmitting a wireless signal, encoding a digital audio signal, and switching to a different wireless signal transmitting channel;
• and
• a first digital RF receiver being electrically connected to the first digital RF transmitter for receiving RF channel information transmitted by the second digital RF transmitter of the digital wireless receiving device;
• and
• the digital wireless receiving device including:
• a second digital RF receiver for receiving encoded digital audio signal transmitted from the first digital RF transmitter, and capable of switching to a different wireless signal receiving channel;
• a receiving quality detector being electrically connected to the second digital RF receiver, and capable of generating an enable signal when it detects the data to be received by the second digital RF receiver is in poor receiving quality;
• a channel selector being electrically connected to the second digital RF receiver for scanning states of different wireless signal channels and generating appropriate RF channel information;
• and
• a second digital RF transmitter being electrically connected to the channel selector and the receiving quality detector;
• whereby when the second digital RF transmitter receives the enable signal transmitted by the receiving quality detector, the second digital RF transmitter generates an RF signal according to the RF channel information generated by the channel selector.
