SUMMARY
The discussion focuses on the operation of an FM transmitter circuit, specifically the role of components in the right half of the circuit. The circuit utilizes a Colpitts oscillator configuration, where L2 and C5 form the tank circuit responsible for generating the carrier frequency. C6 functions as a feedback capacitor to maintain oscillation, while C3 and R5 create a low pass filter to allow human voice frequencies to be modulated and transmitted. The circuit's design effectively demonstrates the principles of frequency modulation using these specific components.
