摘要： An FM stereophonic radio broadcasting system in which stereophonically related audio frequency source signals L and R are matrixed in a matrix network (10) to obtain stereophonic sum and difference signals M and S, respectively. At the transmitter, the difference signal, S, is compressed in a compressor (16), and the S and compressed-S signals modulate two quadrature-related sub-carriers of the same frequency in modulators (14, 18) to develop two double-sideband, suppressed-carrier signals, the frequency of the sub-carriers being sufficiently high to assure a frequency gap between the lower sidebands of the modulated sub-carrier signals and the sum signal M. The M signal, the aforementioned suppressed-carrier signals, and a pilot signal having a frequency which lies within the frequency gap, are combined in an adder (12) and frequency-modulated onto a high frequency carrier for the purpose of transmitting the same to one or more remote receivers (24). The receiver includes an expander (30) for expanding the received compressed signal S, and the expanded difference signal is combined with the received M signal to reproduce the audio frequency source signals L and R. The system increases the broadcast coverage area over that of current biphonic service yet is compatible with existing monophonic and biphonic receivers.

摘要： The invention relates to a method and a device for determining a threshold value (Omax, Omin, OTR) for limiting an output signal of a processing unit to which an input signal is delivered. According to the invention, a level of the input signal is determined and the threshold value (Omax, Omin, OTR) is adjusted in accordance with this level. The adjustment of the threshold value according to the level of the input signal, i.e. the adaptive adjustment of the threshold value, enables transient noises at a level clearly below the maximum value for the threshold value to be limited as well. The use of the inventive method and the inventive device in a hearing aid can therefore significantly increase the comfort of the wearer.

摘要： Techniques for controlling the volumes of multiple audio output devices using a collective (master) volume control and an individual volume control for each audio output device. In one set of embodiments, each individual volume control can be configured to indicate the current absolute volume level of its corresponding audio output device. When the master volume control is manually adjusted, the individual volume controls can be automatically adjusted in a manner proportional to the manual adjustment of the master volume control. In addition, when an individual volume control is manually adjusted to a setting or value that exceeds the master volume control, the master volume control can be automatically adjusted to be equal to, or greater than, the manually adjusted setting for the individual volume control. In this scenario, the other individual volume controls can remain unchanged.
