【摘要】 通过对相位、比例、移相乘积鉴频器的理论分析,给出针对这三种鉴频器的输出方程,三个方程都证明:在谐振点f0附近,输出电压U0的值与频偏Δf成正比.更多还原

【Abstract】 By theoretical analysis on phase,proportion and phrase shifting product discriminator,three kinds of discriminator output equation are produced,which all prove that the output voltage value of U₀ and the frequency error Δf have direct ratio near the resonance point f₀.更多还原
