The TV antenna amplifier circuit is as shown, the input loop is composed of the L1 and C1, and it plays the frequency selection and the impedance matching function. The first level of the amplifier uses the common emitter - common base amplifier circuit, this kind of circuit has the advantages of high stability and small noise coefficient. The second and third stages of the amplifier are the common emitter circuit, each stage has the tuning circuit. In order to make the amplifier to have the wide pass band, the tuning circuit uses the staggered tuning and adds the resistances R14, R6 and R10 in the oscillation loop. The potentiometer RP1 can be used to adjust the gain of the amplifier. Figure 15-41 The circuit of the TV antenna amplifier   (View)

The gas-fog alarm circuit of dual-way thyristors

Published:2011/6/25 21:45:00 Author:qqtang | Keyword: gas-fog alarm, dual-way thyristors

The gas-fog alarm circuit of dual-way thyristors When there is the combustible, the conductance of the TGS308 gas sensor is increasing, and it picks out the voltage with the help of potentiometer RP1, the value of the voltage is from 3V to 20V. The raised voltage is then added on transistor VT1 by the diode and the 4.7kΩ resistor, so VT1 is conducting, which makes the dual thyristor 2N6070A conducting. Because of what described above, the full-wave AC voltage pushes H to generate the sound of 90dB, fulfilling the alarm. H is the 20V AC alarm of Deltal6003168.   (View)

The switching circuit with self-hold function

Published:2011/6/20 8:51:00 Author:Nancy | Keyword: self-hold function, switching circuit

The switching circuit with self-hold function is shown as above. The three photocouplers serve as trigger, self-hold and switch respectively. When there is a start trigger signal added to GY, GG1 conducts, the GY2 and GY3 glow with current flowing through to make GG2 and OG3 conduct. When the trigger signal disappears, GY1 doesn't glow to make GG1 cut off, but GG2 has been conducted, the current of GY2 and GY3 is provided by GG2 path, which is equivalent to saying that the switch continues to connect and the circuit can't recover until the power supply E disappears.   (View)
