Extending Blackman's Formula to Feedback Networks With Multiple Dependent Sources

Extending Blackman's Formula to Feedback Networks With Multiple Dependent Sources

The Blackman's formula for the impedance seen from a pair of arbitrary terminals of a linear feedback network with a single dependent source is extended to the case of linear feedback networks with multiple dependent sources. To reach this aim, we revisit the proof of the Blackman's formul...

Zusammenfassung:The Blackman's formula for the impedance seen from a pair of arbitrary terminals of a linear feedback network with a single dependent source is extended to the case of linear feedback networks with multiple dependent sources. To reach this aim, we revisit the proof of the Blackman's formula, proof it in a similar manner for feedback networks with two dependent sources, and then extend to the case of feedback networks with multiple dependent sources.
