| This paper introduces the design of the low power stereo FM transmitter based on FPGA,realized by the digital PLL principle. The core chip MC145152 is controlled by FPGA. It can automatically change and measure the frequency and display it by LCD. In the meantime it realizes the functions of expanding the frequency, designing the homemade sound barrier, stereo coding etc, which make the design better and more practical. The design is programmed with VHDL and realized in the chip of XC2005PQ-208 Xilinx series. It is proved to be well functioning, and the capability index is good after testing. |
