    Abstract: 在本篇論文中, 我們針對ERMES/FLEX系統之呼叫器中頻鑑頻器, 使用積分三角頻率數位轉換調變(△—Σ Modulation)的技術, 將4 level FSK及2 level FSK的訊號解調成數位信號加以辨識; 並使用 VHDL程式語言描述電路和模擬,且將程式燒寫於ALTERA晶片上加以測試。
    In this paper, we design the IF frequency discriminator for the ERMES/FLEX pager system with the technology of the delta-sigma modulator. This circuit can discriminate the 2/4 level FSK with the digital demodulation method. In this paper, we use the VHDL(Very High Speed Integrated Circuit Hardware Description language) to simulate this circuit. We also do some experimental results to verify the function of the delta-sigma frequency discriminator with the ALTERA chip.
