modem
a digital modulator transforms a digital stream into a radio signal on intermediate frequency (if). a modulator is generally a much simpler device than a demodulator, because it doesn't have to recover symbol and carrier frequencies.









































a demodulator is one of the most important parts of the receiver. the exact structure of the demodulator is defined by a modulation type. however, the fundamental concepts are similar. moreover, it is possible to develop a demodulator which can process signals with different modulation types.

bullet::::10. pass the resultant bit stream on for further processing such as removal of any error-correcting codes.









































as is common to all digital communication systems, the design of both the modulator and demodulator must be done simultaneously. digital modulation schemes are possible because the transmitter-receiver pair has prior knowledge of how data is encoded and represented in the communications system. in all digital communication systems, both the modulator at the transmitter and the demodulator at the receiver are structured so that they perform inverse operations.
