摘要： A radio receiver with a low intermediate frequency has a first mixer stage that can be fed with a modulated input signal and at whose output a complex intermediate frequency signal can be derived. Connected downstream of the first mixer stage is a limiting amplifier at whose output the intermediate frequency signal is present in a discrete-value and continuous-time fashion. A sampling device, for sampling the intermediate frequency signal, and a digital demodulator unit are connected to the output of this limiter. The demodulated input signal can be derived at the output of this digital demodulator unit. The present radio receiver requires a low chip area in conjunction with low power consumption, but offers a high sensitivity and accuracy based on the digitally implemented demodulation.

摘要： A PLL circuit (1) is regulated by means of a digital modulation signal (28) at a first frequency, and is then regulated at a second frequency, by deactivation of the digital modulation signal (28).

摘要： In the case of a trimming method for a PLL circuit operating based on the principle of a two-point modulation, the PLL circuit is locked without any modulation being impressed and then an analog and a digital modulation signal are impressed into the locked PLL circuit. A signal that is characteristic of the PLL control error is tapped from the PLL circuit, and the modulation swing in the analog modulation signal is changed such that the characteristic signal has the same value as before the analog and digital modulation signals were impressed.

摘要： The invention is directed to a receiver arrangement, for example, in a mobile radio, which allows the use of slowly locking phase locked loops for a point-to-point connection between two transceivers, even in the case of a heterodyne receiver structure. The need to change channels between a transmission slot and a reception slot is avoided by virtue of a changeover device being provided for the purpose of interchanging the in-phase and quadrature components at the input side on a down-conversion frequency mixer. This advantageously allows either the upper sideband or the lower sideband of a useful signal to be down-converted without the need to change channel.

摘要： The invention relates to a demodulator and also a demodulation method and enables a reliable demodulation even when the intermediate frequency range overlaps the range of the data frequencies of the signal. For this purpose, a rapidly oscillating output signal is generated from the in-phase signal and also the quadrature signal, the sign of which output signal varies in a manner dependent on the product of the signs of the in-phase signal and of the quadrature signal. Either an XOR gate or a multiplier stage may be used in order to generate an output signal of this type.
