Title: Clip compensation circuit
Inventor: KOMATSU KEIICHI
IPC: H04N5/93
Filed: 1985-08-12
Abstract: PURPOSE:To obtain a clip compensation circuit correcting reproduced waveform distortion with small-sized and inexpensive circuit constitution by extracting a profile from a reproducing video signal, extracting the rising part of the profile by a slice circuit with good S/N and adding the extracted rising part to the reproducing video signal. CONSTITUTION:A video signal clamped at the tip potential of a synchronizing signal is inputted to an input terminal of a video signal. The clamped signal is inputted to a HPF 51, from which only the profile of the video signal is extracted. After the profile signal is amplified to a proper level by an amplifier 52, the result is inputted to the slice circuit 53. Only the rising part of a large amplitude is extracted among the profiles by the circuit 53, the slice output is integrated by an integration circuit 54 and an attenuator 55, attenuated and inputted to an adder circuit 56 as a compensation signal. A clamped reproducing video signal from the input terminal is inputted to one input of the circuit 56. Thus, the compensation signal is superimposed on the reproducing video signal whose profile is unsharpened at the circuit 56 and the compensated reproducing video signal is outputted at the output terminal.

Abstract: PROBLEM TO BE SOLVED: To provide a mounting board which is capable of high speed operation and besides is excellent in heat dissipation and mechanical processability, in a parallel transmission type of optical module of such a constitution that an optical element and an electric element are placed mixedly on a shared mounting board. SOLUTION: When constituting a mounting board by sticking an Si substrate 5 loaded with an optical element 2 such as an LD array or the like to a ceramic board 1, the electric connection to the ceramic board 1 of the optical element 2 is performed through a metallic electrode 9 existing extensively from the surface of the Si substrate to the bottom. A metallic electrode 9 to perform the electric connection to the optical element 2 is made on the Si substrate 5, and the metallic electrode 9 is extended to the bottom of the Si substrate, and it is connected at that section directly to the ceramic board 1, so as compared with a conventional method by wire bonding, highly reliable connection with the wiring inside the ceramic board becomes possible.  Moreover, since wire bonding becomes needless, so the crosstalk is dissolved, and it becomes possible to bring the optical element and the electric element close to each other more than before, and the compatibility to a high-speed signal above gigahertz becomes possible.
