![]() High-frequency transmitters in the UHF and microwave ranges, using new devices such as the The development of radar before and during World War 2 was a great stimulus to the evolution of LITERATURE REVIEW 2 BASIC HISTORY OF FM RADIO TRANSMITTER Offers wider coverage than FM, but frequency modulation is more tolerant of noise and signal ![]() AM is the variation in carrier amplitude relative to the audio signal. Frequency modulation isĪchieved by varying the carrier frequency with changes in the amplitude of the audio signal (i. Using amplitude modulation (AM) and frequency modulation (FM). Modulation of audio signals is typically achieved Large antenna sizes due to high signal attenuation. Transmission of low-frequency signals requires 1: PROBLEM STATEMENTĪudio signals have an inherently low frequency. Slightly varying the radio signal's frequency. In an FM transmitter, the information is added to the radio signal by Transmitter combines the information signal that is to be carried with the RF signal (the carrier). The transmitter is in the form of an electronic signal. The power source is a 9v dc battery, which startsĭischarging after a constant power supply for around 6 hours. Noise component dominates the signal transmitted hence message cannot be received successfullyĪfter a certain distance due to obstacles. Increase our distance from the source, the signal received is merged with noise and furthermore The signal transmitted has a limited range for its reception, as we ![]() A transmitter generates FM waves for various purposes such as communication,īroadcasting a message, etc. The sound, this transmitter transmits the audio signals through the carrier wave by the difference The FM transmitter is a low-power transmitter and it uses FM waves for transmitting 1: BACKGROUNDįM transmitter is an electronic device, which produces frequency-modulated waves with the help One discusses the background of the project, problem description, aims, and objectives. This chapter provides an overview of the project by giving a description of the problem. 2 BASIC HISTORY OF FM RADIO TRANSMITTER.(electromagnetic waves) from the antenna. Such a rapidly reversing current causes him to emit EM waves An electronic circuitĬalled an FM transmitter converts the electrical energy from the battery into high-frequencyĪlternating current (AC). Provides a higher S/N ratio than AM (Amplitude Modulation). Shields signals from unwanted signals, noise, and For example, listening to music forĮntertainment, hearing in distance, or as a tour guide. Power consumption that can be used in a variety of situations. The purpose of this project is to develop a small FM transmitter with low A high voltage spark between two metals was used to create radio This circuit, which assists the antenna and amplifies the electromagnetic signal, essentiallyįunctions as a radio system. Transistor-based circuits are used to generate frequency-modulated signals in FM transmitters.
