  • Methods and apparatus of managing a power amplifier
    Publication number: 20070024356
    Abstract: In the present technique for power management of a power amplifier, an amplifier bank from a plurality of amplifier banks in a power amplifier that has been switched off for a longest period of time is assessed (826) to provide a lowest amplifier bank. With this lowest amplifier bank, an up-threshold that is associated to the lowest amplifier bank is assessed (828), followed by another assessment (820) of a current power output of the power amplifier. It is next determined (830) whether the current power output corresponds at least in a predetermined way to the up-threshold, and if so, the lowest amplifier bank is accordingly switched on (832).

  • Methods and apparatus of managing a power amplifier
    Publication number: 20070024357
    Abstract: In the present technique for power management of a power amplifier, it is first determined (314) whether a counter value corresponds at least in a predetermined way to a counter threshold, and if so, a current status of at least one amplifier bank from a plurality of amplifier banks in a power amplifier is switched (316).

  • Simplified method of attenuation of logarithmically coded digital signals
    Patent number: 5383202
    Abstract: A method is provided of attenuating a signal value within erroneous frames of a logarithmically coded digital signal. The method includes the steps of detecting an erroneous frame of the logarithmically coded digital signal and adding an attenuation value to a frame exponent of the erroneous frame.
