ABSTRACT:
The disclosure relates to improved filter networks for use in the microwave region employing TTL logic and capable of changing a network from a "bandpass state" to an "all-stop state", or an "all pass state", or from a "low-pass state" to an "all pass state". Provision is also made for the increase or decrease in the selectivity of a low-pass filter.
