The selected sig- nal is applied to Q5 whose collector-base capacitance acts as a varactor diode to modulate the audio subcarrier at IC3. The volt output of IC6 powers all analog and digi- tal circuitry except for the tone decoders; the 5-volt output of IC7 takes care of them.

Second, heavy or prolonged voltage surges cause a Zenith Spike Suppressor to cut off power com- pletely to protected equipment thereby signaling the need for datawheet replacement Spike Suppressor. And if you need to learn circuit design before fatasheet to datashest on your own, there are two self-study courses in passive and transistor circuits that will teach this exciting area to you right on the ET The transmitter section generates the RF carrier using a crystal- controlled exciter operating at one-half the assigned frequency.

Basically, the device is an R- C oscillator and a wave shaper. Unlike some Japanese manufacturers, who already are substituting the so-called FST Flat Square Tubes in the smaller sizes Radio-Elec- tronics, OctoberAmerican TV makers have decided to retain the same faceplate curvature as at present in their new squarish models — at least for the time being.

We recently had a chance to review an oscilloscope that fills those requirements and adds some bonuses, including dual-trace capability, the ability to display one sweep at a time, and the ability to store a display. BoxAnn Arbor, Michigan U. There has never been an aircraft accident in the United States which was attributable to an ILS shutdown.

Include payment in full, plus shipping and handling charge. While other manufacturers were busy copying each others designs, BBC looked at where portable meters were used and how they could be improved. Get precise read- outs of average do and true RMS volt- age. Civil aviation got its start in May,when the first bag of air mail left the infield of Belmont Race Track on Long Island the airplane was a Curtiss Jenny and landed three hours and forty minutes 74yc162 on the polo grounds of Washington, D.

The opposite is true of the signals from A 2.

That jumper should be wired as shown on the schematic diagram if you want the frequency counter to always measure the output frequency of the generator. Along with the test signals, sync-gen- erator reference signals LS-TTL com- patible are also available at a rear-panel card edge. A foil pattern for an appropriate board is shown in Fig. Nov 16 – 23, Jul 24, The design I came up with was very similar to Mr.

Our portable scanners keep you in touch with the local news.

Ethics for managements consultans. Foil patterns are shown half-size for the two required double-sided boards in Figs. When choosing your cabinet be sure that it is large enough to accommodate the board and the off-board components com- fortably.

It generates a ramp with independently controlled leading and trailing sides. Coincidentally, there was a 50 percent drop in the reve- nues of Jamaican movie theaters.

It should have a total range of around Hz, regardless of where the coarse frequency control is set. Transistor Q2 also receives composite video from pin 13 of IC3, but with the chrominance information included. Figures 15 and 16 show two practical digital thermometers.

That new tube is expected to measure inches.

One-shot IC3-a determines how long a caller has to dial in the code number. The network made up of C6, C7, R12, and R14 provide a quadra- ture phase relationship between pins 1 and 18 the chroma-lead and -lag pins of the RF modulator. The attaching of dafasheet wires is best done by soldering a two- to three-inch length of bare No. A similar model is expected in the U. Scans within pro- grammed bandwidth.

Figure 1 shows a dtaasheet diagram of the project.

Reserve your Regency HX1 now. Included in that chapter 74gc162 circuits based on a variety of IC timers. It would indeed be diffi- cult to find an oscilloscope that was sig- nificantly smaller than this 3 X 5! SA Call toll-free 4 or outside U.
