2 km FM Transmitter Circuit Diagram, Working and Applications
https://electronicshub.org/fm-transmitter-circuit/
FM Transmitter Circuit Principle: FM transmission is done by the process of audio pre amplification, modulation and then transmission. Here we have adapted the same formula by first amplifying the audio signal, generating a carrier signal using an oscillating and then modulating the carrier signal with the amplified audio signal.
ECE 4760 Final Project: Laser Audio Transmitter
https://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/s2009/dyz2_jl589/dyz2_jl589/index.html
The transmitter is broken down into three circuits. The first circuit, which is similar to the receiver end, is the laser audio transmission circuit. This transmitter works by modulating the amplitude of the laser based on the amplitude of the audio signal that we are trying to transmit. The audio, which is fed to the circuit through a standard 3.5mm audio jack, is sent to an adder circuit.

The transmitter circuit is capable of storing the energy for the oscillation as it is a derived from the (inductor and capacitor) LC circuits. The audio I.e input signal obtained from the mic is passed through the base of the transistor in order to modulate the output signal of the LC circuit in FM (I.e frequency modulation wave) Form.
