Title: Semiconductor circuit device
Inventor: TANAKA MASAHIRO
IPC: H03K5/08
Filed: 1988-10-31
Abstract: PURPOSE:To contrive the improvement of the test accuracy by generating a comparatively high output voltage against a minute voltage required for a test of a discrimination circuit by a test use power source unit P/S, dropping it to the necessary minute voltage by a resistance voltage division and inputting it to the discrimination circuit. CONSTITUTION:At the time of testing a testing circuit 1, a unit P/S is connected to a third pad 5 and a fourth pad 6, and a test voltage ET generated by this unit P/S is applied. The voltage ET is brought to voltage division by each resistance Ra, Rb and Rc of a resistance group 4. The potential of one terminal N1 of the resistance Ra is fetched onto a wiring L1a through a base . emitter T11. The potential of the other terminal N2 of the resistance Ra is fetched onto a wiring L2a through a base . emitter T12. In this state, when it is assumed that characteristics of the base . emitters T11, T12 are uniform, a voltage between the wirings L1a, L2a is equal to a potential difference ERa. This potential difference ERa is applied to terminals A, B of the circuit 1, and the circuit 1 being, for instance, an ECL circuit determines its output logical level in accordance with its potential difference ERa.

Title: Moving vector detector
Inventor: TAKAHAMA KENGO
IPC: H04N5/232
Filed: 1990-10-16
Abstract: PURPOSE:To improve the accuracy of moving vector detection by weighting a moving vector basic data in response to a density gradient in the vicinity of a representative point. CONSTITUTION:A picture signal is fed to an input terminal 10. A representative point memory 18 extracts a representative point from a current field signal and a representative point of a preceding field is stored in a representative point memory 19. A subtractor 21 and an absolute value device 22 calculate correlation between two fields. An absolute difference passes through a weight switch 38 and integrated in an accumulating adder memory 24 by using an adder 23. On the other hand, a density gradient detection circuit 30 calculates density gradient independently in the horizontal and vertical directions. A moving vector detector 25 extracts a moving vector from a position at which an extreme value of the accumulation of the accumulating adder memory 24 is taken. Thus, the effect due to random noise is reduced and the accuracy of moving vector detection is improved.

Abstract: PURPOSE:To prevent deterioration in the demodulation characteristic even with the presence of a frequency offset in a transmission line by providing a loop comprising a bias distortion detection circuit, a distortion averaging circuit and a VCO so as to cancel the bias distortion. CONSTITUTION:When a modulation signal receives the effect of frequency off set fOFF at a transmission line, the mark frequency of a received modulation signal is fz+fOFF and the space frequency is fA+fOFF and a bias distortion is produced in the demodulated data. If the offset fOFF is positive, for example, the distortion where the space of the demodulation data is longer than the bit length of the mark takes place. the distortion is detected by a bias distortion detection circuit 5, an output 1 is outputted, the output of the distortion average circuit 6 is positive and the output of the VCO has a high frequency. Then the lock frequencies fl1(=fz-falpha), Fl2(=f +falpha) of the DPLL2 are increased accordingly. When the frequencies fl1, fl2 reach as fl1approx.=fz-falpha+fOFF and fl2approx.=fA +falpha+fOFF, the bias distortion is nearly zero and the control loop operation is converged. When the offset is negative, the similar control is also applied.
