Digital Audio
The principle of digital audio
Although there are various methods for converting analog signals into discrete digital signals, pulse code modulation (PCM) is commonly used in digital audio systems to convert continuous signals. PCM mode was invented by French A. H. Rivers in 1937 and has long been widely used in communication. With the advancement of semiconductor technology, especially in the stage of ultra large scale integrated circuits, PCM has been applied in the field of audio and has become a reality in households.

The difference between HiFi speakers and AV speakers
The sound effect created by the speaker is surround sound, and its front sound field has no depth, so it can be seen that the placement of the front speaker of the AV speaker is parallel to the display. The imaging power of this type of speaker is not as good as HiFi speakers because it can create grand scenes. To make up for this, a center speaker is added to highlight the sound field of the characters and compensate for the lack of intermediate imaging. In order to increase the sound field momentum, subwoofers are usually equipped, so the difference in sound field is the biggest difference between these two speakers.
