P1 - WC for recording ; Digitalization.
P2 - digital vs analog.
P3 - distortions in digital
1. Which of the following best describes the relationship of the first paragraph to the passage as a whole?
(A) The first paragraph introduces a general thesis that is elaborated on in detail elsewhere in the passage.
(B) The first paragraph presents a concrete instance of a problem that is discussed elsewhere in the passage.
(C) The first paragraph describes a traditional process that is contrasted unfavorably with a newer process described elsewhere in the passage.
(D) The first paragraph presents a dramatic example of the potential of a process that is described elsewhere in the passage. ~~~~~
(E) The first paragraph describes a historic incident that served as the catalyst for developments described elsewhere in the passage.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2. According the passage, one of the ways in which analog recording systems differ from digital recording systems is that analog systems
Analog systems are defined in P2.
(A) can be used to reduce background noise in old recordings --- true but not defined in passage.
(B) record the original sound as a continuous waveform ~~~~~~~correct.
(C) distort the original sound somewhat ---- No
(D) can avoid introducing extraneous and nonmusical sounds - no, even it introduces that.
(E) can reconstruct the original waveform with little loss quality -- No.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3. Which of the following statements about the numbers by which sound is represented in a digital system can be inferred from the passage?
Lines to read - Because the digital playback system “reads” only numbers, any noise and distortion that may accumulate during storage and manipulation of the digitized signal will have little effect: as long as the numbers remain recognizable, the original waveform will be reconstructed with little loss in quality.
(D) They are not readily altered by distortion and noise accumulated as the digital signal is stored and manipulated. - correct
--------------------------------------------
4. Which of the following can be inferred from the passage about the digital approach to the processing of sound?
(A) It was developed in competition with wax-cylinder recording technology. --- it can't be . a generation gap is b/w the two.
(B) It has resulted in the first distortion-free playback system. -- nope.
(C) It has been extensively applied to nonmusical sounds. --- no
(D) It cannot yet process music originally recorded on analog equipment. -- yes it can.
(E) It is not yet capable of reprocessing old recordings in a completely distortion-free manner.- correct
