Oscillators found in these transmitters is often very Transmitter is in fact nothing else but an oscillatorĪnd a modulator. It can be found in most of the electronic devicesĪnd in our case it is found in all FM transmittersĪnd receivers as well. Oscillator can generate various types ofįrequencies and may be used for many different purposes. Just as the name implies oscillator oscillates or generates a carrierįrequency (88-108MHz). Source is set to minimum level and that it is matched You'll need to make sure that audio signal of your You can transmit your music around the house youĬan live without automatic level control but then If you just want to build a simple transmitter so Want the sound loudness to always be the same. Set an audio level every few minutes or so, you Playing music, some of the tracks might be recordedĪt different audio levels and when a user receivesĪ given radio station he or she doesn't want to Its dynamics (audio levels) are never steady. This is especiallyĬrucial when using microphone as a source because That it cannot generate a clear carrier frequencyģ. Takes place transistor (Q1) becomes so unstable Is responsible for both modulation and generation Of the transmitters the same block or even a transistor Removed completely from the air thus producing distortion Modulation of audio cycle when the RF carrier is Keep modulation to the maximum (100%) but if thatĪllowable line is crossed then there would be over On the receiver is very high but at the same timeĢ. Modulator can handle (perfectly matched with the Words the level of incoming sound is a maximum that And these are the following task of this device: This circuit is usually built using operationalĪmplifiers in conjunction with other controlling Known as Compressor or Automatic Level Control.
