11. These steps can be implemented directly in SPICE using the small-signal circuit of hand analysis. 12. Digitally controlled sound chips are also mixed-signal circuits . 13. Such mixed-signal circuits offer smaller size and lower cost, but must carefully account for signal interference. 14. The company designs its analog and mixed-signal circuits in standard CMOS process technology for low-cost manufacturing. 15. His research interests are in the area of high-performance digital and mixed-signal circuit design and high-performance networking. 16. On 12 December 1988, three trains collided near Clapham Junction because a signal circuit had been wrongly wired. 17. Common hardware handshake signals ( hardware flow control ) use the RS-232 RTS / CTS or DTR / DSR signal circuits . 18. Since rail signal circuits must be highly reliable, special techniques are used to detect and prevent failures in the relay system. 19. Some measurements in signal circuits require higher sensitivity movements so as not to load the circuit under test with the meter impedance. 20. On the other hand, since no extra signal circuits are required, XON / XOFF flow control can be done on a 3 wire interface.
