Method and system FPOR transferring data to improve responsiveness when sending large data sets
Most of the internet traffic today is carried out via the Transmission Control Protocol (TCP).

A signal amplifying system comprising: an amplifying module with a plurality of PGAs coupled in series; a test signal generating circuit, for generating a test signal fed to one test input PGA; and a control circuit. If the test input PGA is not a final PGA, the final PGA outputs an output test signal amplified by the test input PGA and the PGA following the test input PGA, wherein each of the PGA following the test input PGA has a known amplifying gain. The control circuit acquires an accumulated gain for the test input PGA and the PGA following the test input PGA based on the output test signal, and acquires an amplifying gain of the test input PGA based on the accumulated gain. |

Method and an apparatus for automatic volume leveling of audio signals
There is provided a method for audio signal adjustment comprising: determining a loudness estimate for at least one frame of an audio signal; determining a level value for the at least one frame based on the loudness estimate; and adjusting the audio signal based on the level value. An apparatus for carrying out the method is also provided. |
