摘要： The present invention relates to a method for carrying out buffering in a digital telecommunication system, wherein data is transferred in frames the length of which is F bits. According to the method, data is written into the buffer memory in synchronism with a write clock signal (WR-CLK), and data is read from the buffer memory in synchronism with a read clock signal (RD-CLK). In order to implement the combined bit and byte buffer in the simplest possible manner, the buffer memory is composed of M pieces of one-bit data memory locations (14; 21), the figure M being selected so that the frame length F is divisible by the figure M and the figure M is divisible by the byte length, and that the synchronization data passed through the buffer is stored in a one-bit synchronization memory location (15; 24) adjacent to one data memory location (14; 21).

摘要： The invention relates to a method for controlling a phase-locked loop in a locking situation, and to a phase-locked loop. The loop comprises a phase detector (13), a loop filter (14) and a voltage-controlled oscillator (15) connected in succession, a feedback path being established from the output of the oscillator to a second input (12) in the phase detector. In response to a change causing a currently used input signal to become inadequate for locking, the signal connected from the loop filter (14) to the oscillator (15) is frozen to a constant value, and in response to a change causing a currently used signal to become again adequate for locking, the freezing is removed. In the method, in order that the locking would take place directly, without any sudden phase changes, (a) the output signal of the loop filter (14) is additionally maintained substantially at said constant value by means of the feedback loop (25; 45) in response to a change causing the currently used input signal to become inadequate for locking; and (b) the control provided by said feedback loop for the loop filter (14) is frozen substantially at its current value in response to a change causing the signal to become again adequate for locking.

摘要： The invention relates to a method and a circuit arrangement for switching on an electric load, in particular a power supply. The load is fed from a voltage source supplying an input voltage (Uac), and an input capacitor (Cin) is connected to the input terminals of the load (107). According to the method, (a) when the input voltage (Uac) is switched on, the operation is in the inrush mode, where the input capacitor (Cin) begins to be charged by means of a charging current (Ic) supplied by a constant-current generator circuit (108), when the input voltage (Uac) has exceeded its minimum value, and (b) after the input capacitor (Cin) is charged, a transition to the continuous mode following the start-up occurs. To switch on the load safely by means of equipment as simple as possible, information about the charging of the input capacitor (Cin) is derived from a change caused in the constant-current generator circuit by a drop in the charging current.
