Signal shaping process and its device

Abstract

The present invention provides a signal shaping method and device which relates to the digital signal processing technology. The signal shaping device is used to do regularized treatment to the input signal format, the device includes a burr filtration unit and a signal width adjustment unit, the input signal passes through the burr treatment unit and the signal width adjustment unit one by one and thereafter outputs to the later grade circuit, among which the burr filtration unit filters the input signals whose effective width are less than the burr width 'N' and keeps the input signals whose effective width are more than or equal to the burr width 'N' certain; the signal width adjustment unit adjusts the input signals to the signals with the regularized width 'M'. In addition, the invention also provides a signal shaping method. The signal shaping method and device of the invention can avoid all kinds of interferences to the circuit in actual environment and effectively simplify the design of the subsequent circuit by doing certain structuring to the input signal format.

Description

technical field [0001] The invention relates to digital signal processing technology, in particular to a signal shaping method and device. Background technique [0002] At present, the integrated circuit industry is in a stage of rapid development, and the application range of integrated circuit products is becoming wider and wider. Accompanied by the environment that integrated circuit products need to adapt to is becoming more and more complex, so the environmental adaptability of integrated circuit products put forward higher requirements. [0003] There are many interferences in the real environment, such as EMI interference, radiation interference, etc. These interferences will greatly affect the signal integrity, resulting in the introduction of burrs on the input signal or unpredictable changes in the format of the input signal. These unpredictable changes may lead to abnormal circuit functions, especially in circuits that need to store input data in a certain format...

[0003] There are many interferences in the real environment, such as EMI interference, radiation interference, etc. These interferences will greatly affect the signal integrity, resulting in the introduction of burrs on the input signal or unpredictable changes in the format of the input signal

These unpredictable changes may lead to abnormal circuit functions, especially in circuits that need to store input data in a certain format based on the input signal, which may cause memory read and write confusion.
