Abstract: The present disclosure relates to an image display system, including a television having a screen, a sound projector, a control unit in signal communication with said screen and said sound projector, said control unit being configured for said sound projector to project one or more audible beams in a room towards one or more target paths. The system includes an optical instrument having a frame and a pair of lenses, detection means and transmission means, said detection means being designed to receive at their input an audio signal having a frequency falling in a 20-20 kHz frequency band and to output a processed signal, said transmission means being designed to receive at their input said processed signal, and to output a calibration signal. The control unit calibrates said sound projector according to said calibration signal generated by said optical instrument.

Abstract: A circuit for controlling frequency and/or phase response characteristic of a signal amplification system or channel has a serial architecture composed of a plurality of cells and a selector for deriving the signal after any one of the cascaded cells. At least one component of the RC network of each cell is in the form of a plurality of elements connected in series, each of the elements having a value which is a fraction of the design value of the component. A short-circuiting switch is associated with each element; the overall effect may be chosen by selecting the derivation node of the output signal and a certain configuration of the short-circuiting switches of the RC networks of the various cells. An outstanding flexibility of selection is achieved.

Abstract: Switching distortion in a digitally controlled attenuator is effectively suppressed and soft-switching in passgate arrays, present at a certain point of a logic signal path, is implemented with a minimum number of additional components. The soft switching in passgate arrays is implemented by driving the control nodes of each passgate by an inverter, at least a current terminal of which is made switchable from the respective supply node to a node onto which an appropriate ramp signal toward the potential of the respective supply potential is produced by a suitable controlled ramp generator. The passgates for switching the current terminals of the inverters are controlled by the logic signal that preexisted the intervening switching on the respective signal line of the passgate, and by its inverse. The preexistent logic value is momentarily stored in a latch that is updated at the end of any new switching process.

Abstract: The dynamic range of operation of a differential transconductance input stage is reduced when the amplitude of the input signal decreases, thus reducing the level of the noise that is generated by the input stage. A DC signal representative of the sensed amplitude of the input signal is employed for either reducing the value of a common, emitter-degenerating resistance or of the bias current that is forced in the two branches of the differential input stage.
