Doing research for my jie

erm she ask me wat type of frequency can control a remote car to a very far distance???

eagle SG

It depends a lot more on the power of the transmitter, not the frequency...

In addition, it also depends on the filtering and authentication algorithm of the remote control car, which if imperfect, may make take in stray signals and go haywire. It will be good to use 16-bit authentication along with some form of simplified CRC algorithms. It may also be good to use a bandpass filter to get a cleaner signal.

You should post this in homework forum for more help

A radio frequency?

Your jie trying to invent some radio-controlled terroristbombing device arh? Evil or Very Mad

must be some sch project la

I did before... Twisted Evil

no la...is her homework...she busy..so ask me help do research wat type can get furthest de... Mr. Green

orh so if wan it go further must see the transmitter…

imagine: what's the use if your transmitter cannot transmit the signal far enough?

The receiver is also important because it must be sensitive to weakened signals. It must also be able to amplify the signals properly before sending it through the circuit. However, through amplification, there may be a lot of noise. Some people may suggest Manchester Encoding, but I personally feel that it is rather useless in this case. As suggested earlier, a bandpass filter would do...

wat abt those RC plane?

eagle SG

it depends heavily on how well u can filter off stray signals. This calls for good filtering algorithms in the code
