摘要
介绍一种新型鉴频器的设计，这种鉴频器成功地应用于倍密度磁记录器中，并较好地解决了多中心频率、大频偏、高频率下的高线性度问题，同时分析了影响鉴频器指标的因素和以往鉴频器的局限性，并给出实验结果。
A new wideband discriminator which has been successfully applied to double density recorder is described. The discriminator can improve linearity of discriminator under high frequency, wide frequency deriation, multi-center-frequency.The factors which influence the specifications of discriminator and the insufficiency of former discriminator are analysed. Finally, the testing results are given.
