Description

technical field [0001] The invention relates to the field of wireless receiving devices, in particular to a multifunctional FM frequency modulation receiver. Background technique [0002] As a relatively ancient communication technology, radio communication technology began to develop at the end of the 19th century, and until today, the technology has developed quite maturely. As the product of this technology, FM transceiver equipment is widely used in civilian and military fields. After more than 80 years of development, this technology has now reached the sunset stage. Although the popularity of the Internet, mobile phones, televisions and other equipment has crowded out the market for FM transceivers such as FM radios and walkie-talkies, there is still much room for development in the fields of aviation communications and natural disasters. Traditional FM receivers, such as radios, have disadvantages such as complex circuits, unstable operation, and volume. Contents ...
