Patent JP-S59174013-A (JP)
Title: Signal processor
Inventor: TACHIBANA YASUO
IPC: H03H17/02
Filed: 1983-03-23
Abstract: PURPOSE:To eliminate the spike type noises contained in an oscillating waveform of a rotary device by making use of a self-recurrence model predictor. CONSTITUTION:A pulse generator 1 produces a synchronizing pulse P in 1/integer cycle of an oscillation waveform. When receiving the pulse P, an A/D converter 2 gives A/D conversion to an oscillation waveform (x) and delivers a signal xk. When receiving this signal xk, a self-recurrence model predictor 3 predicts the present predictive value uk from the past value. A decider 4 compares the signal xk with the value uk to deliver the signal xk and the value uk when the difference of them is smaller and larger than the prescribed value respectively. When receiving this output, a D/A converter 5 converts the output into an analog signal synchronously with the pulse P and delivers it. In such a way, the spike type noises contained in the oscillation waveform of a rotary device can be eliminated.

Title: Extraction controller for teletext data extracting circuit
Inventor: SOBASHIMA HIROSHI
IPC: H04N7/08
Filed: 1987-03-03
Abstract: PURPOSE:To correctly extract teletext data by allowing a clock phase control circuit to switch the phase of an extrating clock when the phase of a character signal is shifted from a normal value and feeding back the detection output of an error rate detecting circuit in its reducing direction. CONSTITUTION:When the phase of a character signal to be sampled is shifted from the normal value to the advanced side or the delayed side due to ghost, group dely, noise, or the like, the detection output of the error rate detecting circuit 15 is changed. An extraction control circuit (CPU) 17 controls a clock phase switching circuit 10 based on the detection output to switch the phase of the extraction clock to the advanced side or the delayed side and controls the feedback of the detection output of the circuit in its reducing direction (error rate reducing direction). Consequently, sampling can be executed at a maximum noise margine state and the teletext data can be correctly extracted.
