How does the digital electronic circuit system realize the editing of sound signal?

Digital electronic circuit system realizes the editing of sound signal by editing the stored data. The sound signal is stored as binary data in the loop.

A piece of sound is usually converted into digital through sampling, quantization, coding and other processes. Generally, fixed frequency sampling is adopted, and the digital size represents the sound at the sampling time. By editing the extraction time and the size of the extracted data, the sound signal can be edited.

Division of digital circuits: According to functions, it can be divided into combinational logic circuits and sequential logic circuits. The output of the former at any time depends only on the input state of the circuit at this time, but has nothing to do with the past state of the circuit, and they have no memory function. Commonly used combinational logic devices include adder, decoder and data selector.

The output of the latter at any time depends not only on the input state of the circuit at the moment, but also on the past state of the circuit, and they have memory function.

According to the structure, it is divided into discrete component circuits and integrated circuits. The former is a circuit that connects independent transistors, resistors and other elements with wires. In the latter, components and wires are fabricated on a semiconductor silicon wafer, packaged in a housing, and lead circuits are soldered. The integration level of integrated circuits is different.
