Title: Timing extracting circuit
Inventor: KONNAI SUEO
IPC: H04L7/033
Filed: 1985-02-22
Abstract: PURPOSE:To obtain a steadily stable sampling clock signal with less jitter by inhibiting an input to a digital phase control circuit of an output signal of a comparator circuit until the output amplitude of a tuning circuit reaches a reference level to a reception burst. CONSTITUTION:An automatic gain control circuit 1 applies line equalization to a signal A functioning as a reception burst and outputs a signal B whose amplitude is constant. The tuning circuit 2 extracts the timing component of the signal B and since the Q is set higher, the signal C is a waveform with slow leading response and a comparator circuit 3 generates a rectangular timing clock signal D from the signal C. When the signal C reaches a reference level, jitter is far less. A burst detection circuit 4 uses the signal B as a trigger to detect the reception burst (signal A) and output a signal E. A delay circuit 5 retards the signal E to output a signal F. An AND circuit 6 ANDs the signals D and F to output the signal G. A digital phase control circuit 7 matches the phase of the sampling clock signal H with that of the signal G.

Abstract: PURPOSE:To dissolve the dispersion of speed in the moving-positioning process of an object by moving the object to a fixed position, giving an optimizing processing to data in which the moving speed for that time is observed, preparing a speed pattern and moving-positioning. CONSTITUTION:When a first seeking ends, magnetic heads 3a-3f are made to seek a specific track fixed in advance, a track passing pulse is read at a position signal generating circuit 7 through a servo lead IC 4 for that time, and the time interval is measured. Next, the observed speed data are stored to a RAM with an optimizing processing given through a microcomputer 9 and a new speed pattern constructed. Then, a signal to indicate that it is available is transmitted to an interface, and after that, the heads 3a-3f are made to execute a seeking action at the speed pattern set newly to the RAM instead of the speed pattern set to a ROM. Thus, the manual adjustment of equipment is made unnecessary, and since the speed pattern is adjusted automatically, the dispersion of the speed in the moving-positioning process of an object can be dissolved.
