Low cost detection of wobble inversions using a tuned circuit

   
   

A tuned circuit is used to detect wobble clock inversions. The tuned circuit reacts to a wobble inversion with a change in amplitude that may be detected by a threshold detector. A bandpass tuned circuit is used to detect wobble clock inversions. The output of the bandpass tuned circuit is input to a saturating high-gain amplifier such as a comparator. The output of the saturating high-gain amplifier reacts to wobble inversions with a half-cycle that has an increased duration as compared to half-cycles without wobble inversions.

Um circuito ajustado é usado detectar inversions do pulso de disparo do balanço. O circuito ajustado reage a um inversion do balanço com uma mudança na amplitude que pode ser detectada por um detetor do ponto inicial. Um circuito ajustado bandpass é usado detectar inversions do pulso de disparo do balanço. A saída do circuito ajustado bandpass input a um amplificador high-gain saturating tal como um comparador. A saída do amplificador high-gain saturating reage aos inversions do balanço com um metade-ciclo que tenha uma duração aumentada em comparação aos metade-ciclos sem inversions do balanço.
