DAB

A tuner is a subsystem that gets radio frequency (RF) transmissions like radio publicizes and converts the selected service frequency and its associated bandwidth into a set frequency this is suitable for further processing, typically due to the fact, a lower frequency is used on the output. Broadcast FM/AM transmissions commonly feed this intermediate frequency immediately into a demodulator that converts the radio signal into audio-frequency signals that can be fed into an amplifier to drive a loudspeaker. More complicated transmissions like pal/NTSC (tv), DAB (virtual radio), DVB-T/DVB-S/DVB-C (digital television) and so on. use a much broader frequency bandwidth, regularly with numerous subcarriers. those are transmitted inside the receiver as an intermediate frequency (IF). the next step is normally either to procedure subcarriers like real radio transmissions or to pattern the entire bandwidth with A/D at a rate quicker than the nyquist rate that is at least 2 instances the IF frequency.
