    摘要: A method for distinguishing speakers in a conference call of a plurality of participants, in which method speech frames of the conference call are received in a receiving unit, which speech frames include encoded speech parameters. At least one parameter of the received speech frames is examined in an audio codec of the receiving unit, and the speech frames are classified to belong to one of the participants, the classification being carried out according to differences in the examined at least one speech parameter. These functions may be carried out in a speaker identification block, which is applicable in various positions of a teleconferencing processing chain. Finally, a spatialization effect is created in a terminal reproducing the audio signal according to notified differences by placing the participants at distinct positions in an acoustical space of the audio signal.

    摘要: An emitter-coupled multivibrator circuit comprises two transistors (Q1, Q2), between which is provided a positive feedback by connecting each transistor base to the collector of the other transistor. In the multivibrator, the transistors (Q1, Q2) are connected to operating voltages via coils (L1, L2, L3, L4) instead of using conventional resistors and current sources. This lowers the necessary operating voltage, since no DC voltage loss is provided across the coils. Additionally, this improvement increases amplification during the avalanche process and thus the speed of the whole circuit. Further, the waveform of a signal is closer to the sinusoidal form at high frequencies. The speed of the circuit can be increased further by providing an electromagnetic coupling between the coils (L1, L2, L3, L4).

    摘要: An emitter-coupled multivibrator circuit comprises two transistors (Q1, Q2), between which a positive feedback is provided by connecting each transistor base via buffer transistors (Q3, Q4) to the collector of the other transistor. In the multivibrator, the transistors (Q1, Q2, Q3, Q4) are connected to operating voltages via coils (L1, L2, L3, L4, L5, L6) instead of using conventional resistors and current sources. This lowers the necessary operating voltage, since no DC voltage loss is provided across the coils. Additionally, this improvement increases amplification during the avalanche process and thus the speed of the whole circuit. Further at high frequencies, the waveform of a signal is closer to a sinusoidal form. The speed of the circuit can be increased further by providing an electromagnetic coupling between the coils (L1, L2, L3, L4, L5, L6).

An indication to change a viewing angle of a first video image of a subject may be received, and in response, a second video image of the subject, captured from a different angle, is displayed. The indication is detected by user input such as selection of an area of an image, movement of a mobile device, or detection of a user's gaze. Display adjustments may be made by zooming and cropping, and audio adjustments may be made by changing a volume associated with an area of an image, allowing for a customizable viewing experience.

    摘要: Methods, devices and a software product for generating a sinusoidal signal of a desired frequency at a desired sampling rate. If the frequency is higher than the upper limit, a coefficient is determined as a function of the sampling rate and a sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is decimated by the sampling rate. If the frequency is lower than the lower limit, the coefficient is determined as a function of the sampling rate and the sample of the first output sample sequence is determined as a linear combination of the coefficient and two previous output samples. The first output sample sequence is multiplied so as to generate a second output sample sequence. The second output sample sequence is decimated by the sampling rate.

    摘要: High speed multivibrator circuits operable with lower operating voltages are disclosed. A multivibrator circuit comprises an operating voltage source, first and second nonlinear amplifier components, each comprising a first and a second main electrode and a control electrode, wherein the first main electrode of the second amplifier component is connected to control the control electrode of the first amplifier component, and the first main electrode of the first amplifier component is connected to control the control electrode of the second amplifier component. A capacitor is connected between the second main electrode of the first and second amplifier components. First and second resistors connect the first main electrode of the first and second amplifier components to a first potential of the operating voltage source. A pull-down circuit is connected between the second main electrodes of the first and second amplifier components and a second potential of the operating voltage source. The pull-down circuit comprises third and fourth amplifier components, acting as active pull-down components which are cross-connected such that they are alternately in conducting and nonconducting states due to forced control by the states of the first and second amplifier components.

    摘要: In a voltage-controlled LC oscillator, a series LC resonance circuit is connected between two transistor amplifying stages which provide low impedance input and output circuits for the LC circuit. The collector of the first transistor stage is connected through a coil to the operating voltage. The emitter of the second transistor stage is connected to the reference voltage through a coil. This will result in narrowband transistor stages and significant advantages in the power consumption and other characteristics of the oscillator.
