Title: Noise removing device
Inventor: UYAMA KAZUYUKI
IPC: H04N5/93
Filed: 1986-03-31
Abstract: PURPOSE:To lower the quantity of noise remaining in a part of video signals after removing noise by raising cut-off frequency of a high-pass filter that extracts high frequency component on which noise component gets in from video signals in a period in which amplitude of high frequency component is above a specified value. CONSTITUTION:The switch SW of a high-pass filter 1 is opened, and cut-off frequency becomes fc1 =1/omegaR1C1. Accordingly, input video signals 100 are inputted to the filter 1 and high frequency component higher than cut-off frequency fc1 is extracted. An amplitude detecting circuit 7 closes the switch SW when the amplitude of high frequency component extracted from the filter became higher than amplitude of noise component. Under this condition, cut-off frequency of the filter 1 becomes fc2, and becomes fc1<fc2. When amplitude of high frequency component becomes smaller than amplitude of noise component on it, an amplitude detecting circuit 6 opens the switch SW. Accordingly, the part where amplitude level of differential waveform of input video signals 100 is large becomes slender. When this is limited by a limiter 2 and finite difference of video signals inputted from a delay circuit 6 is obtained by a difference calculator 3, the noise is reduced.

Title: Fault diagnostic circuit
Inventor: IKUTA KOJI
IPC: G06F11/22
Filed: 1990-03-20
Abstract: PURPOSE:To reduce the circuit scale by using a comparison timing pulse to compare held input data and read data with each other at the time when data corresponding to held input data is read out from a memory means. CONSTITUTION:Address data out of data written in a memory means 1 is held in a data holding and comparing means 5 by a holding timing pulse, and the comparison timing is used to detect coincidence/disaccord between read data and held data when address data is read out. Since an (N+1)-ary counter means 4 has a period one clock longer than that of an N-ary counter means 2, next address data in the memory means 1 is held in the data holding and comparing means 5 just after data comparison. That is, the address to be held and com pared is successively shifted by the (N+1)-clock period to diagnose all addresses. Thus, it is unnecessary to hold data of all addresses, and the circuit scale is reduced.
