Introduction to Latest RF ATE with Low Test Cost Solutions

This paper describes latest RF Automated Test Equipment (RF ATE) technologies that include device under test (DUT) connections, a calibration method, and an RF test module mainly focusing on low cost of test (COT). Most important respect for low COT is how achieve a number of simultaneous measurements and short test time as well as a plain calibration. We realized these respects by a newly prop...

Introduction to Model theory

These notes aim at giving the basic definitions and results from model theory. My intention in writing them, is that they should provide the reader with many examples, even with some proofs, and contain most of the definitions. Differences in vocabulary can be quite an obstacle to mutual understanding, and having the terminology written up somewhere should prove helpful. An index is included at...

Introduction to Ergodic theory

Let Σ be a finite set. Recall from the previous setup that we have an abelian group G acting on the set Σ of functions G→ Σ. For a function ω ∈ Σ, this G-action is given by (g · ω)(h) = ω(g + h), h ∈ G For today, G = Z, the integers with the group operation of addition. We will think of Z as parametrizing the action of time. We set Ω := ΣZ. We would like to put an interesting metric on Ω, to st...

Introduction to Springer theory

(d) Hm−∗(M,M \X), where M is a smooth oriented manifold of dimension m and there exists an embedding X ↪→M as before. (d’) Hm−∗(X) if X itself is a smooth oriented manifold of dimension m. (e) H∗(D•(X), d). Assume there exists an embedding X ↪→M to a smooth manifold M of dimension m. Then we define D•(X) be a chain complex of distributions supported on X. (A distributions of degree k is a conti...
