Tiếng Anh chuyên ngành Viễn thông - Unit 1 (part 3): Electronics in the home. The main contents of this chapter include all of the following: Reading for a purpose, understanding diagrams, describing block diagrams and circuits, describing diagrams. | TASK 8 Looking now at the basic units of the circuit we can describe the volume control like this The volume control consists of a ten-microfarad electrolytic capacitor connected in series with a five-kilohm potentiometer pot . The positive terminal of the capacitor is connected to the output of the AF amplifier and the wiper of the pot is connected to the power amp. The 5 third terminal of the pot is connected to the zero voltage supply rail which is earthed. positive pozotiv terminal torminl output autput wiper waipo rail reil TASK 9 Fill in the gaps in this description of the tuned circuit shown in Fig. 2. Each gap represents one word. The circuit1 of a four hundred and seventy2________________ inductor which is connected in parallel with a capacitor. The 4 can be varied between five and sixty-fives ______________The aerial is ________to the top end of the tuner. It is also connected to the positive terminal of the in the detector. The bottom end of the tuner is connected to earth via the zero voltage 8__rail. TASK 10 Speaking practice Work in pairs A and B. Complete your circuit diagram with help from your partner. Ask questions like these What kind of component is Pl What s the value of Cl What is connected between the collector of Q2 and the positive side of the battery If you don t understand your partner say I m sorry Ĩ don t understand. Could you say that again please Could you speak more slowly If your partner doesn t understand you at first try phrasing your answer in a different way. For example It s a variable resistor. It s a resistor which you can vary or change by turning the control. It s called a variable resistor. Student A Your circuit diagram is on page I 74. Student B Your circuit diagram is on page .
