摘要：
A precise clock frequency is required to obtain a precisely defined passband for the filter. A circuit is disclosed herein to provide an adjustable passband filter utilizing switched capacitor filters. The circuit employs voltage-controlled oscillators which can be selectively set to any one of several desired frequencies to obtain the variable passband characteristics for the resultant filter.
