摘要
Abstract
To solve the problems of low stability of center frequency,large temperature drift, low production efficiency in mass production, and poor product consistency of the analog frequency discriminator, a novel digital frequency discriminator with high performance is designed based on digital intergrated circuit (IC) in the paper. Many experimental results show that the novel frequency discriminator has the advantages of high frequency discrimination sensitivity which does not vary with temperature, improving production efficiency and guaranteeing product consistency.关键词
