More information about digital
signals versus analog signals: |
| |
Sound inherently begins and ends as an analog signal; it is
a wave pulse that can be distorted if not converted immediately
into a digital format. In order for the benefits of digital
audio to be achieved, the integrity of the signal during transmission
must be preserved. The conversion process at both ends of the
chain must also be highly efficient and with low quality loss
in order to ensure pure sonic fidelity. |
| |
Digital audio signals travel from a digital source such as
a CD or a PC's S/P DIF output to the amplifier. In some cases
it passes through an analog amplifier where the signal is converted
from digital into analog via DAC (Digital Analog Converter).
On the abit iDome, which has a digital input,
the digital source remains digital and is amplified while in
this purely digital format. |
