good day sir!
1).I am now currently doing a simple project about transmitting and recieving ir wavelengths. i just want to know from the knowledgable ones on how to transmit an ir signal with its corresponding signal frequency.for example if i transmit a 4kHz freuquency of ir signal how can i detect the same frequency using a receiver circuit.
2).If i use a 555 timer to generate the transmitter frequency is there any circuit configuration that would process the receiving signal from the transmitter?
3).Another questions sir is that if the desired ciruits is achieved with their corresponding signal frequency allocation is there any possibilities that the receiver will activate if i uses another transmitter with different frequency? because during my experimentations i have an ir receiver or the phototransistor i use 2 different remote controllers from our tv and dvd player and it activates the receiver what i want to know is that is it possible to have frequency allocations on IR spectrum..
thank you sir....
