Embodiment Construction

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0033] In the prior art, digital signal processing is a key part of signal processing. Common digital signals are generally in the form of binary signals, for example, "0" represents a low level, and "1" represents a high level. Among them, binary digital signals have different basic forms according to different classification methods. For example, there are two types of unipolar codes and bipolar codes in terms of amplitude values, and whether the signal voltage or signal curren...

Abstract

The invention provides a signal modulation circuit, a signal modulation chip and a signal modulation device. The signal modulation circuit comprises a first modulation module which is configured to select a first target level signal from a plurality of first level signals, and generate a first modulation signal according to the first target level signal; and a second modulation module which is electrically connected with the first modulation module and configured to select a second target level signal from the first modulation signal and at least one second level signal, generate a second modulation signal according to the second target level signal and output the second modulation signal. The signal modulation circuit can form multi-state transmission in digital signal processing.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a signal modulation circuit, a signal modulation chip and a signal modulation device. Background technique [0002] In the prior art, digital signal processing is a key part of signal processing. Common digital signals are generally in the form of binary signals, for example, "0" represents a low level, and "1" represents a high level. Among them, binary digital signals have different basic forms according to different classification methods. For example, there are two types of unipolar codes and bipolar codes in terms of amplitude values, and whether the signal voltage or signal current occupies the entire symbol. During the duration, it is divided into two categories: return-to-zero code and non-return-to-zero code. [0003] However, the existing binary signal form can no longer meet the diverse needs of users, and how to form multi-state transmission in digital signal p...
