TL;DR: In this paper, the zwitterionic structure of α-aminophosphinic acids has been supported by the appearance of the characteristic absorption of the NH 3 ⋯ anion system and by the detection of characteristic v (antisym., sym.)PO 2 vibration frequencies of the (PO 2 ) group.

TL;DR: In this article, a reciprocal gyrator-capacitor section with reference to integrated realisations is proposed, containing four grounded gyrators and four capacitors, which realises any complex 2nd-order even-part zero of a driving-point admittance and reduces the degree of the admittance function by four.
Abstract: A reciprocal gyrator-capacitor section is proposed with reference to integrated realisations. The section, containing four grounded gyrators and four capacitors, realises any complex 2nd-order even-part zero of a driving-point admittance and reduces the degree of the admittance function by four. The element values of the section are given in the terms of the extracted transmission zero and the value of the admittance function at the extracted zero.
