When it comes to the rc car transmitter, many confusions arise. It is the last stage of signal processing in the transmitting equipment. The same applies to the receiving team. For more information, see the documentation of the recipient.
What is a transmitter?
A transmitter is simply a circuit responsible for sending in some way the information that is applied at its input through a means to a remote receiver. It makes no interpretation of the signal is at the entrance, just send it handles efficiently through the environment for which it was designed. If by my rough definition of above is not clear that the circuit does a radio transmitter, we explain in terms of radio electronics.
A rc car transmitter receives information from an earlier call encoder or signal generator based on r / c, from now on we will call encoder simply because it is more simple. This electronic signal modulates the RF output which is characteristic of the transmitter. The transmitter usually consists of a kiss, a signal amplifier stages and finally a filter.
A radio transmitter is always making the signal frequency increase with the purpose to exploit the characteristics of radio waves of high frequency (HF) and Very High Frequency (VHF), which propagate with very good and small antenna efficiency and the environment through known. For this reason it does not vary at all from a common radio transmitter as handy VHF or a cordless phone.
In addition, rc car transmitter may help to decide whether the signal appearing at its input sends it on AM or FM. The circuit design module makes the signal amplitude or frequency, regardless of their origin, meaning that no matter how computer data, voice, signal, etc.
Oscillator
Information on the Internet is plagued oscillators, there are many publications that the best on the subject. I'm just going to do stress upon those normally used in radio circuits. Basically an oscillator is a circuit that generates high frequencies which are then used in the later stages. They are only used in the transmitters, but also in the recipients (see section receptors) and the most used in our circuits are those that use a quartz crystal as the main element. From there we will see that the sales teams use a pair of glasses, one for the rc car transmitter and the other for the receiver. This can be totally interesting! Prove it on your own.
