Filed: 1987-01-24
Abstract: PURPOSE:To attain high speed convergence with high accuracy and a small circuit scale by using an IIR filter circuit whose stability is guaranteed, removing roughly waveform distortion and using an adaptive FIR filter so as to equalize the residual equalization with high accuracy. CONSTITUTION:A signal incoming from the subscriber line is inputted to an input terminal 1 and converted into a digital signal by an A/D conversion circuit 2. This signal selects the filtering coefficient of a coefficient control circuit 3 for the IIR filtering circuit in response to the level of the input signal to decide the equalizing characteristic of the IIR filter circuit 4. Then the inputted signal is subjected to rough equalization in the IIR filtering circuit 4. Then the signal is equalized with high accuracy by the FIR filtering circuit coefficient control circuit 5 and the adaptive FIR filtering circuit 6 to remove the attenuation distortion and phase distortion, and the result is outputted from an output terminal 7. Thus, the equalization is subjected to stable high speed conversion with high accuracy by a few number of times of operation processings.

Title: Recording medium
Inventor: SAKO YOICHIRO
IPC: G11B7/24082
Filed: 1990-01-25
Abstract: PURPOSE:To reduce crosstalk with adjacent tracks and to improve CN ratio, etc., by forming a control data recording area with narrower track width than the track of a data recording area and forming the data recording area with larger track width. CONSTITUTION:The control data recording area (a) is made to have smaller groove width than that of the data recording area (b). This prevents crosstalk which adversely affects reproduction of data in the grooves in which the control data is recorded in the form of displacement in the width direction, even when displacement in the width direction is given too near to another displacement. Namely, the control data recording area (a) in the track T2 is narrower than the data recording area (b) of 1.0mum width even when 0.2mum displacement in the width direction in the area (a) is added to the original 0.6mum width, which prevents crosstalk between the adjacent tracks T1 and T2. On the other hand, by forming the area (b) wider than the area (a), the groove width for recording data by magneto-optical signals can be made large, which improves the CN ratio and error rate of reproduction.

IPC: G01F1/66
Filed: 1985-01-30
Abstract: PURPOSE:To eliminate misdetection of propagation time difference between received waves, by detecting the first bottom level of the first received signal and the second crest level of the second received wave to take a balance between the received waves. CONSTITUTION:Received waves 5 from an upstream side ultrasonic vibrator 2 and a downstream side ultrasonic vibrator 3 are fed to a received wave switchgear 26, the output signal 30 of which is sent out as received wave 32 already balanced while a part thereof is introduced to a first comparator 33, where it is compared with the bottom threshold 35 to obtain a binary-coded signal 36. Likewise, the second crest is compared with the threshold 39 to obtain a binary coded signal 40. Then, the thresholds 35 and 39 change with a microcomputer 28 according to the signals 36 and 40 to detect the first bottom level A1 of the first received wave and the second crest level B1 of the second received wave. Then, an AGC voltage 42 is sent to an AGC amplifier 10 from the microcomputer 28 while an offset voltage 44 is added to an operational amplifier 27 to take a balance between received waves. Thus, the rate of hourly change will be the same from the first bottom to the second crest between both the received waves thereby eliminating error in the propagation time difference.
