Title: Timing signal recovery by superheterodyne phase-locked loop
Inventor: FISCHER MICHAEL C
IPC: G11B20/10
Filed: 2001-10-19
Abstract: PROBLEM TO BE SOLVED: To eliminate cost restrictions laid down on at least the phase linearity of a required filter at the time when a filtering and synchronous detection attendant on the reproduction of phase-locked carrier waves is made to approach an optimal performance so as to demodulate addresses or other information carried by timing reference signals which are of the least jitters and isolated. SOLUTION: A circuit that recovers timing reference signals contains a superheterodyne phase-locked loop. The recovery circuit can dispense with a phase linear filter that has a high percentage of bandwidth, and a filter whose center frequency to pass is substantially fixed can be arranged at a point of the recovery circuit. Through the recovery circuit constituted as above, the filter is narrowed in bandwidth and can be adjusted so as to be coincident with the modulation characteristics of the timing recovery signals. By this setup, an excellent signal/noise ratio can be obtained through a limiter and a phase detector, and the phase-locked loop is improved in performance.

Filed: 2001-11-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide an illumination device for photography that can easily obtain prescribed optical performance even when light emitting elements are arranged in any shape, extend the service life of a light source and reduce the power consumption.  <P>SOLUTION: The illumination device for photography employs a plurality of white LEDs arranged as a light source and emits the light emitted from the white LEDs through a filter externally. Thus, the bluish light emitted from the white LEDs can be converted into white light close to the sunray and the device can be configured by using the white LEDs of one kind. Since it is enough to consider only the illuminance without taking into account a color tone for the arrangement of the light emitting elements in this way, the device can easily obtain prescribed optical performance even when the light emitting elements are arranged in any form. Moreover, since the device employs the white LEDs for the light source, the service life of the light source can be extended and the power consumption can be reduced.  <P>COPYRIGHT: (C)2003,JPO
