RF transmitter? so ibig sabihin po ay wireless.
kelangan mo po ng digital modulator, pinakasimple is FSK technique.kc ang principle po nyan ay ganito:
'yong binary data (stream of 1 and 0) ang modulating signal mo then kelangan mo ng RF carrier signal. magko-combine ang dalawang signal sa modulator to produce two frequencies for the modulated signal, one that represents 1 and the other represents 0 (space and mark frequencies). to recover the binary info u nid an FSK demodulator.
aside from FSK, marami pa po digital modulation techniques.
