Abstract: Embodiments of a method and a system for generating a received signal strength indicator (RSSI) value that corresponds to a radio frequency (RF) signal are disclosed. In an embodiment, a method for generating an RSSI value that corresponds to an RF signal involves obtaining an attenuation factor code in response to applying an automatic gain control (AGC) operation to the RF signal, obtaining an analog-to-digital converter (ADC) code in response to applying an ADC operation to a signal that results from the AGC operation, and combining the attenuation factor code and the ADC code to generate an RSSI value. Other embodiments are also described.

Abstract: An RF feedback receiver arrangement includes a reference signal provider configured to provide, in a normal operating phase, a first reference signal having a first reference signal frequency, and provide, in a calibration operating phase, a second reference signal having a second reference signal frequency different from the first reference signal frequency. In addition, the RF feedback receiver arrangement includes a signal property detector configured to detect a transmit signal property of the transmit signal in the normal operating phase based on combining the first reference signal with a transmit signal or with a signal derived from the transmit signal, and to obtain, in the calibration operating phase, a calibration signal based on combining the second reference signal with the transmit signal or the signal derived from the transmit signal, which describes a disturbing portion introduced into the detected transmit signal property by the RF feedback receiver arrangement itself.

Abstract: A printing press has at least one first printing tower with at least one first printing unit that has several offset printing couples which are usable to print on one or on both sides of a first web which runs through the first printing unit substantially from the bottom to the top. The web is printed in multiple colors in the first printing tower. A dryer is arranged downstream of the first printing unit and along the conveying path of the first web. A former structure, with at least one former through which the web runs, is located downstream of the dryer. At least one nipping roller is located downstream of the dryer and upstream of the former. A spreading device is provided between the dryer and the at least one nipping roller that is located upstream of the former and along the conveying path of the first web.

Abstract: A mixer arrangement includes a mixer cell coupled by a signal input to a mixer input, and is embodied for frequency conversion of a signal present on the input side to an intermediate frequency. A first current source is coupled to the signal input of the mixer cell, and a second current source is coupled to a signal output of the mixer cell. The mixer arrangement furthermore includes a sensor circuit embodied for detection and for outputting of a value which is derived from a current of one of the current sources. A desired value regulating circuit is coupled by a feedback input to the sensor circuit and is designed for outputting a regulating signal to the one current source derived from a comparison of a signal present at a feedback input with a desired value.

Abstract: A filter arrangement comprises a switching element coupled to a filter input, wherein the switching element is controllable by a reference clock signal. The filter arrangement further comprises an input storage element, an output storage element, and a first and a second auxiliary storage element. The first and the second auxiliary storage element can each be connected in parallel to the input storage element or to the output storage element depending on a switching signal. The output storage element is coupled to a filter output. The filter arrangement can be used as a loop filter in an analog-to-digital converter, wherein the output signal of the filter arrangement is quantized to provide an output word. Respective feedback signals can be generated from the output word and be provided to the storage elements.

Abstract: Provision is made of a differential amplifier arrangement with a current source (S1), two controllable paths (T1, T2), which are in each case coupled by one terminal to the current source (S1) and the control terminals of which form the input of the differential amplifier arrangement. Via a respective cascode circuit (K1, K2), a load (L1, L2) is respectively connected to the first and second controllable paths (T1, T2). At least one tap (A1) between one of the loads and one of the cascode circuits forms an output of the differential amplifier arrangement. Provision is made of a comparison means (D1) having two inputs, which is designed for outputting a control signal dependent on a comparison. A first input is coupled to the first tap (A1) and the second input is designed for feeding a reference signal.
