High isolation RF signal selection switches

A selection switch with high isolation between RF signal input terminals is achieved with a gated Schmitt trigger circuit feeding into a control NAND gate in each signal switching channel. The control NAND gates of the separate signal channels are coupled to an output terminal by a single NAND gate. The schmitt trigger circuits and all gates are implemented with Schottky transistor-transistor logic circuits having input clamping diodes. Each Schmitt trigger circuit includes two cascaded NAND gates and a feedback isolation Schottky diode between one input terminal connected to receive an RF input and another input terminal connected to receive a feedback signal from the second of the two cascaded NAND gates. Both NAND gates of the Schmitt trigger circuits are enabled by the same switch control signal which enables the control gates

Schmitt trigger multivibrator

Schmitt trigger multivibrator circuit, capable of astable, monostable or bistable operation, incorporates an input circuit in conjunction with a Schmitt trigger circuit. The circuits form two output signal levels, are useful in switching circuit applications, initiates oscillations, and forms highly unsymmetrical wave forms

Something to Die for. The Individual as Interruption of the Political in Carl Schmitt’s The Concept of the Political

This article aims to question the anti-individualist stance in Carl Schmitt's concept of the political by uncovering the historical bias of Schmitt's anti-individualism, seen here as one of the main driving forces behind his argument. For Schmitt, the political can take place only when a collectivity is able to declare war to another collectivity on the basis of feeling existentially threatened by the latter. As such, Schmitt's framework implies the inescapable possibility of war, as the condition which makes possible the political. Acknowledging the previous criticisms of Schmitt raised by John Rawls and Iris Marion Young, this article takes a different path by pointing to certain historically tacit assumptions in 1927 Germany which Schmitt took for granted, but which are not suitable for a contemporary political theory. The demonstration is done first by showing how the structure of interruption functions in the works of Schmitt, then showing how he conceives of the individual as a possible interruption of the political in history, and then placing this structure of interruption in the historical context of Schmitt's writing

A counter-mine that explodes silently: Romano and Schmitt on the unity of the legal order

This contribution is intended to provide an answer to a controversial question: Why does Carl Schmitt – perhaps the firmest advocate of the state unity – not only mention and praise Santi Romano’s book on the legal order – a work that can be rightfully considered an uncompromising defence of legal pluralism – but even list him among his inspirers? While a given (and essentially flawed) interpretation of Romano’s institutional model, like that provided by Schmitt, actually makes his concrete-order thinking better suited to cope with the legal pluralism of modern social theory (and this is a possible answer to the opening question), it ultimately reveals the serious deficiencies of what can be defined as Schmitt’s institutional decisionism. Contrary to what Schmitt believes, indeed, Romano’s social ontology decisively contributes to demonstrate how the argument Schmitt uses in his general attack on social pluralism can also be re-deployed in its defence. Yet, Schmitt’s reappraisal of Romano’s concept of institution, questionable as it may be, addresses and tackles a crucial issue – probably, the crucial issue of both the entire book and his legal institutionalism as a whole – that Romano himself appears to be unable to solve and that still remains an open and challenging question for most social theorists

Islamist Terrorism in Carl Schmitt's Reading

The thought of Carl Schmitt (1888-1985) helps to place Islamist terrorism within a certain tradition of warfare and political theory. In fact, this form of violence can be clarified by Schmitt’s theoretical endowment, as this brief paper attempts to do. The end of the legal framework of the jus publicum europaeum and the emergence of non-state actors have put into question centuries-old certainties. Schmitt’s theory could help to put order in political concepts today ideologically misused. And his opposition to any universalistic tendencies questions not only Jihadi ideology but also Western anti-terroristic rhetoric, which is equally part of the ongoing global war of annihilation feared by Schmitt during his entire life

Deploy diverse renewables to save tropical rivers.

A strategic mix of solar, wind and storage technologies around river basins would be safer and cheaper than building large dams, argue Rafael J. P. Schmitt, Noah Kittner and colleagues
