PURPOSE:To obtain high selectivity by providing plural selective information input devices and an operating device operating plural output signals of the said input devices and separating object information from unnecessary information. CONSTITUTION:An information source including the object information (x) and the unnecessary information (y) is inputted to the selective information input devices 4a and 4b having respectively the selectivity characteristic of information processing functions f(x,y) and g(x,y). Thus, an information component circuit 5a outputs the object information component fx(x,y) and the unnecessary information component fy(x,y). The same is true for an information component circuit 5b. Then an operating device 6 operates the object information components fx(x,y) and gx(x,y) and the unnecessary information components fy(x,y) and gy(x,y). Thus, an output device can output an object information component hx(x,y) and an unnecessary information component hy(x,y). In this case, since an operating function f(f,g) is set optionally, the selectivity of the ratio (S/ N ratio) of the said hx(f,g)/hy(f,g) is increased optionally theoretically. |
