摘要： In signal sources with high impedance, generally a capacitive signal source , such as capacitor microphone capsules, amplifying circuits are generally used which, along with the actual amplifier having a high-resistance, non-inverting input, also comprise means for coupling signals and for determining operating points. In order to adjust the operating point of the signal source and the amplifier, separate bias sources are provided which are respectively coupled to the signal source or the non-inverted input of the amplifier via a mutual impedance. At least one coupling capacitance is situated in the signal path between the signal source and the non-inverting input of the amplifier. In order to increase noise considerably using one such amplifying circuit, without the disadvantage of very high idle times, the mutual impedances are formed from a non-linear resistance (D1, D2 or D3, D4) and an ohmic resistance (R3 or R4) respectively connected in series thereto. Furthermore, the output signal (S2) of the amplifier (IC1) or a signal derived therefrom is coupled back to the mutual impedances (D1, D2, R3 or D3, D4, R4) via a second or third coupling capacitance (C3 or C4).

摘要： Mikrofone, welche von einer Stromversorgungsquelle auf normierte Weise, beispielsweise in Phantomschaltung, gespeist werden, enthalten üblicherweise eine Mikrofonkapsel, einen der Mikrofonkapsel nachgeschalteten Verstärker zum Treiben einer von Mikrofonausgang belastenden Impedanz und eine Koppeleinrichtung zum Übertragen der von der Stromversorgungsquelle bereitgestellten Gleichspannung an den Verstärker. Zur Impedanzanpassung eines derartigen Mikrofons unter Vermeidung eines Transformators im NF-Signalweg wird vorgeschlagen, in den Übertragungsweg zwischen der Koppeleinrichtung und dem Verstärker einen Gleichspannungswandler zum Erzeugen einer belastungsgerecht angepaßten Betriebsspannung für den Verstärker anzuordnen.

摘要： The invention relates to a method for converting an analogous input signal (S1) into a digital output signal (S7). The analogous input signal (S1) is amplified in a first signal path (2, 3, 5) and is subject to an analog-to-digital conversion (5). An additional analogous signal (S4) is obtained in a second signal path (4, 6) for transmitting greater signal amplitudes. Said signal (S4) is subject to an analog-to-digital conversion (6). The signal (S5) that is digitised in the first signal path (2, 3, 5) and the signal (S6) that is digitised in the second signal path (4, 6) are supplied to a digital signal processor (7) which generates the digital output signal (S7). The aim of the invention is to prevent abrupt reduction of the signal resolution and to obtain a dynamic range that is as high as possible. The analogous signal that is supplied to the second signal path (4, 6) is distorted in a non-linear manner and in an opposite direction in relation to the reinforced analogous signal (S2) in the first signal path (2, 3, 5). The differential amplification of the first and second signal path thus increases above a pre-determined threshold and when the signal amplitude increases. An undistorted output signal (S7) is thus produced after the distorted partial signals have been put together.

摘要： To facilitate direct conversion to digital form of an acoustic signal acting on the acoustic receptor of an acoustic receiver while satisfying requirements of dynamic range, noise and adequate quantisation, the following is proposed: the acoustic receptor should be exposed to a counter-signal when the acoustic signal acts on it in such a way that the acoustic receptor is largely maintained in its rest state despite the action of the acoustic signal. The counter-signal is derived from the control variable of a control circuit (1, 2, 3, 4, 5, 6, 7.1 - 7.N, 8) which is a component of the acoustic receptor (2). The control variable contains the information on the acting acoustic signal. Any deviation of the receptor from its rest state immediately generates a digital 'nought' or 'one'.
