Abstract: PURPOSE:To reduce greatly the number of arithmetic circuits, by turning the complex signal of a time-division multiplex signal into a noncyclic digital filter signal in correspondence to channels and then synthesizing the noncyclic digital output signal connected to the output side to change it into a frequency-divided multiplex signal. CONSTITUTION:The outputs Y1r, Y1i, Y2r and Y2i of a noncyclic digital FIR filter having a 16kHz action of the time-division multiplex TDM signal are applied to input terminals 4-1-4-4 and then added together through adders 4-5-4-8.

The outputs of these adders are synthesized by a synthesizing circuit 4-17 via multiplying circuits 4-15 and 4-16 to be delivered in the form of a frequency-divided FDM signal. In this case, the output is calculated just with every two times through the filters 4-9-4-12 to reduce the number of arithmetic circuits down to 1/2. In the same way, the number of arithmetic circuits can be reduced also in case the FDM signal is converted into the TDM signal.

Abstract: PURPOSE:To attain a highly accurate track signal by satisfying specified conditions between focal length of a coupling lens, half-power whole angle of outgoing angle in the direction parallel to joint face of semiconductor laser, focal length of an objective and numerical aperture and specifying the half- power whole angle of outgoing angle. CONSTITUTION:When focal length of a coupling lens is fc, half-power whole angle of outgoing angle in the direction parallel to the joint face of semiconductor laser is theta, focal length of an objective is f0 and numerical aperture is NA0, conditions shown in the expression are satisfied and half-power whole angle thetaof outgoing angle is made to less than 11 deg.. In this case, a beam shaping optical system is not interposed between the coupling lens 2 and objective 5. Generally, it is necessary to make incident beam diameter d1=2f0.NA0 larger than effective diameter of the objective d2=2fc.NAc, and accordingly, relation fc.NAc>=f0.NA0 is required. Thus, beam shaping is made unnecessary, and highly accurate track signal can be obtained and the device can be miniaturized.
