<P>PROBLEM TO BE SOLVED: To provide a fluctuation correction unit and a fluctuation correcting method for correcting time delays due to a fluctuation caused by the communication environment, etc. <P>SOLUTION: A gate array for outputting a CODEC start pulse C-INT according to a synchronous frame pulse FLMCLK received by a communication terminal comprises an internal pulse generator 301 for outputting a pulse, when a timer 351 having a specified time period times up or the synchronous frame pulse FLMCLK is inputted; a fluctuation width allowance generator 303 for generating allowance of the fluctuation width of the synchronous frame pulse; a synchronous frame pulse allowance decision unit for deciding whether the fluctuation width of the synchronous frame pulse lies within an allowable range; a CODEC start pulse generator 307 for synchronously generating the CODEC start pulse C-INT with the synchronous frame pulse, if the fluctuation width lies within or out of the allowable range, respectively; and an offset unit 309 for delaying the CODEC start pulse by a fixed time to output it. <P>COPYRIGHT: (C)2004,JPO |
