Abstract: PURPOSE:To secure a differential characteristic within an area in use, and to improve an S/N, and an error rate, by setting the cut-off frequency of a coupling element larger than a frequency set as the upper limit of the area in use. CONSTITUTION:A medium noide nM is superimposed 2 on the reproduced output of a magnetic head 1 from a terminal 3, and it is supplied to a step-up transformer 4 having a low-pass area cut-off chararcteristic. The number of windings of a coil is reduced, and an inductance L is set at a small value, and when the area in use is in f1<f<fZ. the cur-off frequency is decided at fC larger than the upper limit frequency fZ. Thereby, a gradient is set at 6dB/oct below the frequency fC, and the differential characteristic in the area in use can be secured, and an amplitude is flattened beyond the frequency fC. An amplifier noise nA is superimposed 6 from a terminal 7 after amplification 5, and it is binarized 9, and outputted 10 by a prescribed threshold value through an LPF8. An amplified noise component nA item in a noise power in a differential detection reproducing system by the above constitution is especially reduced, and the S/N can be improved.

Title: Noise processing system
Inventor: FURUKAWA TOSHIHIRO
IPC: H04B1/12
Filed: 1983-11-02
Abstract: PURPOSE:To eliminate surely noise independently of a treated signal by using a pseudo noise generating filter functioning adaptively so as to apply noise processing. CONSTITUTION:A white noise r(k) is inputted to unit delay devices 2 connected in multi-stage via an adder 1, its output is inputted to a multiplier 3 having variable multipliers a1-an and the result of multiplication is summed at an adder 5. The result is inputted to an adder 1, where it is added to the white noise r(k) so as to obtain a filter output signal (pseudo noise) n'(k). Then the pseudo noise n'(k) is added to a unsteady state signal comprising an information signal s(k) and the noise n(k) to form a signal e(k). The coefficient from the signal e(k) is fed back to each multiplier 3 so as to minimize the square mean value E[e<2>(k)] of the signals e(k). Thus, the noise is eliminated surely independently of the treated signal.

Abstract: PURPOSE:To obtain the I-L characteristic of high linearity by forming the adjacency of an edge plane of a resonator waveguide of a semiconductor laser element as a current non-injection region for preventing the deterioration of the edge plane due to Joule heat and accordingly exciting that region by the emitted light of an LED operating part to reduce the adsorption of laser beam in the region.

In an active layer 36 over the V-groove 33, laser oscillation operation starts by using an edge plane where a waveguide is formed by cleaving as a resonance plane. In a window region near the resonance edge plane, a current path is not formed and that region becomes a current non- injection region to produce a light absorption action. Meanwhile, the active layer 36 over the groove 33 operates as an LED by the current injected from the V-grooves 34 located in four position, right and left edges of the V-channel groove 33, and the emitted light propagates in the active layer 36 and is injected into a window region of a laser oscillation waveguide.
