    Abstract: A receiver for a radio broadcast signal, in particular a car radio, and a method for receiving a radio broadcast signal, including a signal decoder for decoding an audio signal contained in the radio broadcast signal in encoded form, and/or for decoding a data signal contained in the radio broadcast signal in encoded form, the signal decoder being operable so that the encoded signal is only decoded, when the signal decoder obtains an external authentication signal, which is received via an external transmission path that is different from the transmission path of the radio broadcast signal.

    Abstract: The digital filter includes a first multiplier (2) receiving an input signal, an adder (3) connected to the first multiplier (2) to receive its output signal, a delay element (6) connected to the adder (3) to receive its output signal, a second multiplier (7) connected between the delay element (6) and a second input of the adder (3) in a feedback branch, a device (16) for supplying either of two values (K1.1, K1.2) of a first multiplier coefficient to the first multiplier (2) and a device (17) for supplying either of two values (K2.1, K2.2) of a second multiplier coefficient to the second multiplier (7). The second one (K2.2) of the two values of the second multiplier coefficient is advantageously 0, while the second one (K1.2) of the first multiplier coefficient values is equal to a quotient of a predetermined first one of the first multiplier coefficient values and a difference between one and a predetermined first one of the second multiplier coefficient values.

    Abstract: In a circuit for suppressing short-lived noise phenomena in a digital audio signal, in particular during a temporary test reception of another transmitter, the audio signal is multiplied by a factor which, prior to the appearance of the noise phenomenon, is brought from a maximum value to a minimum value in accordance with a predetermined time function, and at the end of the noise phenomenon, is returned to a maximum value. The invention has special application to the Radio Data System defined by the European Broadcasting Union, and the testing of "Alternative Frequencies" in that system.

    Abstract: The invention relates to a method for producing an injection valve for liquids, preferably an injection valve for injecting fuel into a combustion chamber of an internal combustion engine. The injection valve has a valve body, with a valve seat which is formed therein, and a valve needle which interacts with the valve seat in order to open and close at least one injection opening. The injection valve is produced by means of the following method steps: producing the valve body from steel, hardening the valve body, annealing a partial region of the valve body at an annealing temperature. The device for carrying out the method according to the invention has an inductive annealing generator which generates a suitable alternating current for operating a coil, in the magnetic field of which coil the valve body can be heated for annealing.
