Abstract: An oscillator is disclosed that is tunable to discrete values, and includes a tuning element which can be connected via a switching device. A rectifier circuit is connected to the output of the oscillator and forms a clock signal from the oscillator signal. The oscillator circuit contains a phase delay circuit having a switching input, a clock signal input which is coupled to the output of the rectifier circuit, and a switching output coupled to the switching device. The phase delay circuit has a comparison circuit for comparison of a phase of the clock signal that is applied to the signal input with a reference phase. This phase delay circuit is designed to emit a switching signal after application of an activation signal to the switching input and after the phase of the clock signal which is applied to the signal input matches the reference phase. In consequence, the switching process is delayed until the step-function response of the output signal of the oscillator does not cause a sudden phase change in the clock signal.

Abstract: The present invention relates to a receiving apparatus for a mobile communications system which can be modulated using different modulation types at the transmitter end. According to one embodiment of the invention, in the middle of a data burst of a Bluetooth communications system, a GFSK modulation method is switched to an M-DPSK modulation method, which is used for the payload data. A frequency offset estimation unit is provided for GFSK-modulated signals in a first receiving section and estimates the frequency offset by averaging over a bit sequence of a trailer of a data burst. The frequency offset is corrected in a second receiving section, by means of a frequency correction unit which operates on the basis of the CORDIC algorithm.

A signal applied to the first and second signal paths is amplified and demodulated on the first signal path. Concurrently, the signal is amplified on the second signal path with a gain factor, and a power of the signal amplified by the second signal path is determined and used for determining the gain factor. A signal conditioning circuit has first and second signal paths and a first and a second operating state. In the first operating state, the first signal path is arranged for amplification for a demodulation, and the second signal path is arranged for amplification for determination of a power of the signal present. In the second operating state, one of the two signal paths is inactive and the other is arranged for demodulating the signal present.

Abstract: A polar modulator contains a phase locked loop which is designed to emit a radio-frequency signal at one frequency to one output, with the frequency being derived from the reference signal and from a phase modulation signal at a control input of the phase locked loop. The modulator additionally has a second signal input for supplying an amplitude modulation signal. The second signal input is connected to a control input of a pulse width modulator, one of whose signal inputs is coupled to the output of the phase locked loop. The pulse width modulator is designed to vary the duty ratio of a signal which is applied to the signal input, with this variation being adjustable via a regulation signal at the control input. A filter can be connected downstream from the output of the pulse width modulator and suppresses higher harmonic components in a signal which can be tapped off at the output of the pulse width modulator. The amplitude of an output signal is thus modulated by carrying out pulse width modulation and by subsequent suppression of higher-level frequency components.

Abstract: The invention is directed to a phase locked loop with a ΣΔ modulator. A multimodulus divider in the feedback path of the PLL is actuated by the ΣΔ modulator. The latter has a design which can be described by a complex transfer function H(s) in the Laplace plane, said transfer function having a complex-conjugate pair of pole points. The arrangement allows a significant reduction in the noise in critical frequency domains and hence allows adherence to transmission masks based on radio specification even when the PLL bandwidth is as large as the modulation bandwidth.

Abstract: The invention specifies a circuit arrangement with a phase locked loop (1), which can be used as a mobile radio transmitter, in particular. The reference frequency for the PLL (1), which is provided by means of the source (3), is multiplied by a multiplier (10) and is down-converted to an intermediate-frequency level in a down-conversion mixer (9) using the output signal from the PLL, and is evaluated such that a modulator (13) connected to the input of the oscillator (6) can be trimmed. The inventive principle is used to advantage in two-point modulators and allows inexpensive, integratable mobile radio transmitters with good noise characteristics.

Abstract: A method and an arrangement for processing a received signal which comprises phase-shift modulated or amplitude-quadrature modulated part-signals which are transmitted in a plurality of different frequency bands, wherein the received signal is processed in a plurality of stages in succession, by multiplying all the input signals to each of the stages by two mutually orthogonal signals in each case to form two intermediate signals in each case, wherein the intermediate signals from one stage in each case act as the input signals to whichever is the succeeding stage in the particular case and the received signal acts as the input signal to the first stage, and wherein an in-phase and/or an quadrature component of the individual part-signals in the different frequency bands are determined from the intermediate signals from the last stage. Parallel, simultaneous reception of a plurality of frequency bands can be implemented relatively easily in this way.
