| 摘要 |
The invention relates to an apparatus for frequency and phase acquisition having a voltage-controlled oscillator (VCO) (10) and a search generator (18) with a forward path (16) and a backward path (20) for generating a search signal with a search frequency, the forward path (16) of the search generator (18) acting as a loop filter when the frequency is locked off, wherein means (24) for automatically symmetrizing the search signal are provided. |
