.. bits, and also operate in a more analog mode as shown in this Design Idea, which pinpoints the location of a break in a wire. First let’s look at the use of CMOS gates as memory devices. Figure 1 shows a one-bit transparent latch. A ...
.. system) but uses a solid-state device to measure magnetic field strength. So, to begin the calibration task, I connected a wire to a bench power supply; one end to the + output and the other end to the output. Next, I set the power supply to ...
.. ferrite core (part no. TN 16/9.6/6.3-3C85) with a secondary winding comprising five turns of 0.2-mm 2 insulated copper wire. (Philips, however, has discontinued the 3C85 ferrite core. Ferroxcube's type 3C90 ferrite may serve as a ...
.. temperature, causing a variation in the diode's voltage drop (Figure 1). This principle is similar to that used in hot-wire anemometers. Figure 1. When cooled by an applied fluid flow, a heated diode increases its forward voltage. You ...
.. 1. Pushing the on switch S 1 or S 2 for approximately 1 sec inserts the 12 V zener diodes D 1 or D 2 in series with the hot wire of the power line. During the push, the polarity-dependent conduction of the zener diodes creates a small ...
.. after the full-bridge rectifier decouples the power supply. The two coil antennas use five turns of 1-mm enameled-copper wire in a rectangular, 50×60 mm shape. As an improvement, if your application requires greater distance, you can ...
.. thermal time constant of about three seconds. Also, solid-state sensor durability is better than that of delicate hot-wire sensors. A detail of Figure 2 worthy of mention is Q 3 , which I include to preclude the possibility of the A 2 ...
.. because it has high gain and low noise; any other transistor with the same characteristics is suitable. A 2- or 3-in. long wire attaches to the output and acts as an antenna. The conversion from audio or video to FM takes place in the ...
.. to calibrate and debug a data-acquisition system to verify basic functionality. The brute-force approach would be to wire all the sensors to the front-end board and use an environmental chamber to set the temperature of the RTDs. An ...
