PCM (Pulse-code modulation) Pulse coding modulation, pcm Pulse Coding modulation
In audio processing, we often hear PCM data. What is PCM Data?PCM data is a digital signal after the analog signal passes through PCM. PCM is the process of converting the audio signal from analog signal (time continuous, value continuous) to digital signal (time discrete, value discrete. Digital signals have many advantages,

Names)
Naming is most helpful for understanding the logical structure of a program. A name description is "what" is more important than "how. Naming can avoid exposing the underlying implementation, thus retaining an abstract layer, simplifying the complexity of the program. For example, you can use getnextstudent () in
Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities:
