The circuit consists of few discrete components. The audio signal is picked up by the microphone which converts the signal into a voltage waveform. This signal is then fed to the transistor Q1 after blocking the DC component. Capacitor C2 blocks the DC component while allowing the AC component to pass. Transistor Q1 amplifies this signal.
ECE 4760 Final Project: Laser Audio Transmitter
https://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/s2009/dyz2_jl589/dyz2_jl589/
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.
TV Transmitter Circuit Working and Applications
https://www.electronicshub.org/tv-transmitter-circuit/
How to Operate TV Transmitter Circuit? Initially connect the circuit as shown in the circuit diagram. Apply a voltage of 12v through a battery to the circuit. Now the audio input is applied to the base of the transistor. The transistor pre amplifies the audio signal and is applied to the RF transformer. Video signal is applied at the input of the video.
