摘要:
An insulation package to reduce the transmission of heat and/or noise between the outer skin and the cabin lining of an aircraft composed of an insulating material enclosed by an encapsulating membrane. The encapsulating material has a vapor diffusion resistance (sd value) at least partially dependent on the ambient humidity, and for a gradient of relative humidity across the encapsulating membrane of 3% to 50% it has a vapor diffusion resistance (sd value) of at least 0.8 m and for a gradient of relative humidity across the encapsulating membrane of 50% to 93% it has a maximum vapor diffusion resistance (sd value) of 0.3 m.

A transmission circuit includes a shift circuit, a second shift circuit, and a modulation circuit. The shift circuit is configured to select a shift amount according to shift parameters and to introduce the shift amount in a first direction into in phase and quadrature phase baseband signals. The second circuit is configured to selectively introduce the shift amount in a second direction into local oscillator signals. The modulation circuit is configured to modulate the shifted baseband signals onto the shifted local oscillator signals to generate a composite modulated output signal. Unwanted components of the output signal are shifted away from original or specified limits. Wanted components of the output signal are unshifted.
