A method of determining the phase distortion ϕ caused by a device under test comprises the steps:
referencing (S100) the phase of a distorted response signal Y R (t) of said device under test (6) provided with a test signal Y T (t) to a coordinate system (S) being in phase with said test signal Y T (t), measuring (S200) the amplitudes M s , M i and M q of several signals Y R (t), Y i (t), Y q (t) depending on signals Y IP (t), Y QP (t) characterising the two coordinate axes of said coordinate system (S), on said distorted response Y R (t) signal and/or on said test signal Y T (t), calculating (S80) the two coordinates S X , S Y of said distorted response signal Y R (t) in said coordinate system (S) on the basis of said measured amplitudes M s , M i and M q and determining (S90) said phase distortion ϕ by calculating said phase on the basis of said two coordinates S X , S Y .

In order to display the amplitude distortions of a transmission channel, the amplitude distribution of a measurement signal of a known amplitude distribution is measured at the output of the transmission channel. Based on a given multitude of amplitude measured values that are measured and digitized in succession, the frequency of occurrence of the amplitude distribution is then determined and displayed in adjacently connected amplitude windows.

The present invention relates to a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer provided. The invention aims to such an object that chill feeling to a human body upon application and in the initial service period, which is a problem of a water-containing hydrophilic gel, is reduced to provide a heat-generating body suitable for using as a heat-generating sheet agent or the like having a water-soluble hydrophilic gel cohesive agent layer excellent in usability, which is a heat-generating body containing a heat-generating composition causing a heat-generating reaction in the presence of air sealed in an air permeable container body having a desired shape, such as a bag form, a sheet form and the like, and a cohesive layer containing water-containing hydrophilic gel agent obtained from a hydrophilic polymer thickener provided on the container body, characterized in that the water containing hydrophilic gel agent contains an organic filler.

Die Erfindung betrifft ein mit einer Wärmeschutzschicht beschichtetes Substrat mit einer Metallschicht (3). Die Wärmeschutzschicht weist eine dielektrische Unterschicht (2) auf, die zwischen der Metallschicht (3) und dem Substrat (1) angeordnet ist. Die dielektrische Unterschicht (2) umfasst zumindest eine erste Lage (2a) eines Oxids oder Nitrids von einem Element einer Gruppe bestehend aus Bi, W, Ti. Die Wärmeschutzschicht umfasst ferner eine dielektrische Oberschicht (4), die auf der von dem Substrat (1) abgewandten Seite der Metallschicht (3) angeordnet ist, wobei die dielektrische Oberschicht (4) zumindest eine Lage (4b) eines Nitrids oder Oxynitrids eines Elements aus der Gruppe bestehend aus Al, Si oder Zr aufweist.
