The system consists of the control module, FM audio module, power module and power amplifier module. The The microprocessing system microcontroller. The singlechip has e out since the 1970s, pared to is valued people39。 本設(shè)計另一核心采用的是 TEA5767 芯片，它是由 PHILIPS公司推出的針對低電壓應(yīng)用的單芯片數(shù)字調(diào)諧 FM 立體聲收音機芯片。本設(shè)計采用模塊化設(shè)計，整個系統(tǒng)由控制模塊， FM 音頻模塊，電源模塊和功放模塊組成。未處理系統(tǒng)采用單片機控制。 TEA5767 芯片內(nèi)集成了完整的 IF 頻率選擇和鑒頻系統(tǒng)，就可實現(xiàn) FM收音機的全部功能。s and the attention by the extremely high performance price, therefore the application is very broad, the development is very quick.
