  • Variable bandwidth pass-band filter
    Patent number: 4151474
    Abstract: In a switched multipath filter network, the passband is varied by varying the duty cycle of the switches which commutate the constituent filters. When no filter is operative, the output connection of the filters is interrupted to prevent the unfiltered signal passing through, but the network output is smoothed to provide sample and hold action.
