摘要： The invention relates to a method of establishing a PWM-modulated output signal representation (OS), providing a stream of parallelly determined intersection representations (PIR) on the basis of a stream of parallel reference signal representation (PRSR) and an input signal (IS), establishing a serial PWM output signal representation (OS) by transforming said stream of parallelly determined intersection representations (PIR) into a stream of serial intersection representations (SIR) by means of a relative time shift of at least one of said parallelly determined intersections (PIR). According to an embodiment of the invention, an advantageous way of providing intersection estimates has been obtained, as each or at least a number of intersection estimates between a reference signal and an input signal may be established partially while taking only the individual partial reference functions into consideration.

摘要： The invention relates to a switching amplifier comprising at least one pulse modulator arranged for modulating at least one input utility signal into at least one pulse modulated signal and at least one switching power stage arranged to establish at least one amplified utility signal on the basis of said at least one pulse modulated signal and a power signal, said power signal being delivered by a tracking power supply at least partly controlled by said at least one input utility signal, characterized in that said switching amplifier is arranged to process said at least one input utility signal according to a correction signal established by a correction signal estimator on the basis of a supply information signal derived from said tracking power supply.According to the present invention an advantageous switching amplifier enabling use of a tracking power supply is provided. Thereby the many benefits of switching amplifiers can now be obtained together with the benefits of utilizing a tracking power supply. Among many things, this reduces power consumption, reduces EMI noise and enables using more of the dynamic range available for the utility signal during the pulse modulation. The last advantage further renders noise introduced by the power supply and the switching output stage less significant, as the signal-to-noise ratio in the power stage is greatly improved due to the utilization of the full dynamic range enabled by using a tracking power supply.

摘要： The invention relates to a high-mode self-oscillating pulse modulator. According to the invention, a complete rethinking of preconditions for oscillation and modulation in an oscillating modulator as all conventional thinking of how to apply oscillation in a modulator has been set aside. Thus, according to the invention, high-mode oscillation refers to an oscillation at a higher mode than the first mode, which is conventionally regarded as the one and only applicable mode in an oscillating modulator.

摘要： An apparatus for processing auscultation signals, e.g. embedded in an electronic stethoscope with a digital readout of an estimated heart rate. The apparatus comprises a bias processor for receiving an auscultation signal and providing a biased auscultation signal; said bias processor comprising an envelope detector and an estimator for calculating a signal representative of the beat frequency of the auscultation signal. In one aspect the information in the biased auscultation signal that is in conformity with the repeated information in the auscultation signal is enhanced. This may e.g. be done by calculating the conformity between the biased auscultation and at least a part of the biased auscultation signal. In another aspect of the invention the auscultation signal is biased by means of A-weighing. Preferably the two aspects of the invention are combined.
