摘要:

AbstractGiven ann‐port of nullityq, theZ‐matrix of which is to be sought, we first construct a primitiveZ‐matrix of orderq, and then apply to it the pivotal condensations with respect toq–nunspecified ports, one at a time. The present note discusses the problem of decomposing a network into blocks and then of seeking a port structure so that any pair of unspecified ports taken from different blocks have no coupling in the primitiveZ‐matrix. This enables us to apply a block‐pivoted condensation to the primit

摘要:

AbstractA second‐order minimum‐phase RC‐active filter with complex transmission zeros is presented. It employs one operational amplifier and is based on a well‐known Sallen and Key resonator. By including an additional difference amplifier a second‐order all‐pass circuit is derived. Both networks have free network parameters which can be used for minimizing the sensitivities of theQ‐factors of the po
