I. Experimental purpose: Figure 1 is the structural diagram of the AM transmission system in the experiment. Understand and master through experiments
AM transmission system, understand and master LC three-point oscillator circuit, triode amplitude modulation circuit, high frequency
Figure 1 Structure diagram of AM transmission system
2. Preview content:
1. Give a complete structure diagram of AM transmission system.
Figure 1 is just a simpler launch system used in the experiment. Consider and give a more complete launch system structure.
2.LC three-point oscillator circuit
Figure T3-1 is an LC three-point oscillator circuit. You are familiar with the circuit and discuss its principle. Think and answer the following questions:
A. Which components determine the oscillation frequency?
