A tuner is a subsystem that receives radio frequency (RF) transmissions like radio broadcasts and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output. Broadcast FM/AM transmissions usually feed this intermediate frequency (IF) directly into a demodulator that convert the radio signal into audio-frequency signals that can be fed into an amplifier to drive a loudspeaker. More complex transmissions like PAL/NTSC (TV), DAB (digital radio), DVB-T/DVB-S/DVB-C (digital TV) etc. uses a wider frequency bandwidth, often with several subcarriers. These are transmitted inside the receiver as an intermediate frequency (IF). The next step is usually either to process subcarriers like real radio transmissions or to sample the whole bandwidth with A/D at a rate faster than the nyquist rate that is at least 2 times the IF frequency.
The term tuner can also refer to a radio receiver or standalone audio component that are part of an audio system, to be connected to a separate amplifier. The verb "tuning" in radio contexts means adjusting the radio receiver to receive the desired radio signal carrier frequency that a particular radio station uses.
Joshua Paul "Josh" Davis (born June 29, 1972), better known by his stage name DJ Shadow, is an American music producer and DJ. He is a prominent figure in the development of instrumental hip hop and first gained notice with the release of his highly acclaimed debut album Endtroducing...... He has an exceptionally large personal record collection, with over 60,000 records.
DJ Shadow was experimenting with a four-track recorder while in high school in Davis, California, and began his music career as a disc jockey for the University of California, Davis campus radio station KDVS. During this period he was significant in developing the experimental hip hop style associated with the London-based Mo' Wax record label. His early singles, including "In/Flux" and "Lost and Found (S.F.L.)", were genre-bending works of art merging elements of funk, rock, hip hop, ambient, jazz, soul, and used-bin found records. Andy Pemberton, a music journalist writing for Mixmag, coined the term "trip hop" in June 1994 to describe Shadow's "In/Flux" single and similar tracks being spun in London clubs at the time. Though his music is hard to categorize, his early contributions were certainly important for alternative hip hop. He has cited Kurtis Mantronik, Steinski, and Prince Paul as influences on his sample-based sound, further claiming that "lyrics (...) were confining, too specific". His music rarely features more than short clips of voices or vocal work.
You heard Osama got a weather machine
bought a new umbrella with my color the screen
and sadam act like the mafia Don
dont touch that dial we run to Vietnam
cool calm on a recon mission
out the work place been gone fishing
heading upstream make you forget home
hungry man dinner chronic fatigue syndrome
you all alone no one to relate to
like even your old lady act askew
world on crutches limping on it's axis
grandpa pitch a tent doing his taxes
scared tactics loop under the mattress
I got guns and internet access
pop divas do drugs and act rude
wear pretty little clothes dance and drop school
I'm makin moves in the land of milk and honey
overcast day nose still runny
come rain and shine please remain calm
dont touch that dial they're gonna drop the bombs.
now this just in
take one on the chin
hip hop mischief huckulbery fin
chuckles and laughs form poisonous gas
second class citizen take two and pass
natives are restless express slang
got excess baggage still love cocaine
hard to maintain harder to let go
they fucking up my city for vendettas and patrol
retro fitted got loop juice aquited
pitted against all odds still committed
hair loss silicone botox kiss' is call
1 800 I am dead in crysis
act now later way to hate fast lose too late!
so your homegirl's up in harms in harms way
red alert bring the alarm bombs away
duck and cover you might get burned
ive seen a thousand points of no return
tune in your now rocking with the calm
dont touch that dial they're gonna touch the bombs
you got them post war blues
still confused
daytime drama sitcom news
still buried in the trenches refuse to loose
aroused from the capitol with rights to choose
product placement
sex is tasteless
still less filling the enemies faceless
a joke in the office and he aint all that
and the new American pastime is rap
stop the presses look another titty
got your homeboy and aint life pretty?
we all rock synthetics to bear the cold
you act like rellox but your barely old
ultra violence a moment of silence
from down with the king to down with the tyrants
cant trust the system we still cant count
cause they bucking down kids when school is out
head for the hills another cold front chill
collection of sorrow and unpaid bills
detonation read a new nation
