A method for demodulating a multiplexed stereophonic signal, the signal including a signal called the sum signal, a signal called the difference signal, and a pilot signal, the method including the following steps: removing the pilot frequency from the multiplexed stereophonic signal, the resulting signal being called the pilotless signal, and subtracting the sum signal from the pilotless signal.

Embodiments are disclosed of methods and systems for providing information in a single FM tuner system. An example method according to the disclosure provides station information in a single FM tuner system, and comprises receiving radio data system (RDS) data/radio broadcast data system (RBDS) data by the single FM tuner system; extracting frequency information regarding receivable stations from the received RDS/RBDS data and displaying a list of the receivable frequencies; extracting additional information regarding the receivable stations from the received RDS/RBDS data, and displaying the extracted additional information regarding the receivable stations in correspondence with the respective receivable frequencies in the list. Further a single FM tuner system is provided for carrying out the method.

A portable wireless sound system comprising at least two speakers is provided. A first speaker is determined to be a host speaker by having a wireless connection to a source device, such that the host speaker receives audio data from the connected source device, outputs the audio data signal, and plays audio. One or speakers are determine to be a satellite speaker by not having a connection to a source device, such that the satellite speakers receive audio data from the host speaker and play audio.

A method for generating a tone signal (TS) having a tone frequency, f, wherein the method comprises the following steps: supplying (S1) a binary bit stream (BBS) having a mark pattern with a supply bit rate, BR, to a signal filter unit; and filtering (S2) the supplied binary bit stream (BBS) by said signal filter unit to generate the tone signal (TS), wherein the mark pattern of the binary bit stream (BBS) supplied to said signal filter unit is adapted to minimize a ratio of the supply bit rate, BR, to the tone frequency, f, of the generated tone signal (TS).
