NOTCH REJECTION FILTER |
摘要 |
<p>The filter is of a bridged-T construction, and includes a pair of semiconductor rectifiers in back-to-back relationship. An oscillation voltage is applied to the junction of the rectifiers to vary their reverse biases and the junction capacities they exhibit. The variations in notch frequency which result are selected to overlap possible drift in filter tuning and provide continued signal rejection in the presence of such changes.</p> |
