摘要： A reproduced signal is digitized so as to count a time interval of a specified pattern simultaneously with the count of a clock period of a phase lock loop circuit. A phase lock loop clock frequency is subjected to a feedback control based on the information indicated the difference between the time interval and the clock period. In this manner, a frequency loop performs a feedback operation so that a frequency of the reproduced signal falls within a capture range of a phase lock-in, thereby increasing the speed of phase lock-in.

摘要： A phase error between an information signal including a reference signal that can be detected asynchronously and a synchronized signal that is synchronously produced from the information signal is detected, and a signal in response to an absolute value of the phase error is produced. Further, a defect detecting signal is produced in response to the absolute value of the phase error. Therefore, whether a pulse signal exceeding a maximum value of the pulse width of the information signal, that is, a pulse signal exceeding the pulse width of the reference signal, is detected or not, it is possible to detect that the signal reproduction enters a defect region immediately after the entry. Accordingly, a defect with noise or a track jumping can be detected rapidly. Furthermore, an information transition interval of the information signal is measured for a prescribed period of time, and the defect detecting signal is terminated in response to a measured value of a time length of the reference signal that is detected in the prescribed period of time, in other words, the passing of the signal reproduction through the defect region is detected with reference to the synchronization of the reference signal. Therefore, pseudo locking of a PLL is avoided when it is operated again, and the PLL can be accurately re-locked.

摘要： A microphone unit comprises a microphone, leg members and a base. The microphone comprises a diaphragm for detecting sound and a housing for containing the diaphragm. The leg members project outwardly from a rear wall of the housing, and are provided near a second through-hole which connects a second inner space to outer space. The base is connected to the leg members to form a gap between the housing and the base. When the microphone unit thus formed in a simple structure and reduced thickness is mounted in a product, the gap allows the outer space to be connected to the second inner space through the second through-hole, making it possible to efficiently guide sound to the second inner space and obtain good differential characteristics.
