hi everyone...
just wanna know...what kind of Tx would be suitable for digital audio optical communication system? and may i know the basic requirements to develop such system?
tq
hi everyone...
can encoder itself generate input signal b4 the data being modulated with the carrier and transmit?since there's oscillator in it.

is it a dip switch is a must ?
hi everyone !!!
well...anyone can tell any website telling bout IR sensor...from the basic info...to its application [motion (of vehicle such as train etc) detection].
tq
thanks :)
yup...only modulated signal can be encoded.
as the transmitted signal received by the Rx...it will be decoded by the decoder.
i would be glad if there's more u guys wanna tell me...bout the dip switch n encoder/decoder.tq
well, just to add...
from what i know....the function of encoder and decoder are to prevent the stray signal of the same frequency. so that, the Rx will only receive the transmitted signal, not other signal of the same frequency. rite ?
so....what's the function of the dip switch in this matter ?
hoe to decode signal with decoder of ht12d
well...hehe......myself also not so sure....:|
Added after 8 minutes:
ok...
then, someone explain to me what's actually the purpose of encoder/decoder in RF transmission ?
and what's actually the application for dip switch ? maybe...u can relate...
decoder php lockit
hi, everyone !
well...i'm thinking of a system for a project. basically the idea goes like this: for the transmission part; it consists of RF Tx module, encoder and dip switch. the dip switch will set the transmitter address, rite ? this address has to match with the...
