Abstract

The embodiments of the invention provide a waveform mapping device. The device comprises a waveform data storage module, a line field time sequence generation module, a data conversion module and an RGB conversion module. The waveform data storage module is used for storing the waveform data of one or more channels to be displayed. The line field time sequence generation module is used for readingthe waveform data to be displayed through generating a read enable signal. The data conversion module is used for converting the amplitude values of each waveform point in the waveform data into a line number value. The comparison module is used to compare the line number value of a current waveform point with the line number value of a current display point when point display or line display isperformed. The RGB conversion module is used for lightening the current display point to be with a preset color according to a priority value of the current display point. By using the device, storageresources can be saved and cost is reduced, and a waveform display mapping processing speed is fast and efficiency is high. The embodiments of the invention also provide a waveform mapping method anda computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a waveform mapping method, device and computer-readable storage medium. Background technique [0002] When using a spectrum analyzer to observe the spectrum of a signal, the display of the spectrum waveform generally adopts the display method of line display, that is, the spectral lines displayed on the screen are continuous. However, for the spectrum trace obtained by digital signal processing method, it is composed of discrete points, for example, the spectrum obtained by DFT or FFT, because its data are equal-spaced sampling points on the frequency axis of the continuous spectrum , so it is not continuous on the frequency axis. However, for the convenience of observation, each discrete point will be connected for display by means of interpolation during display. figure 1 and figure 2 Example diagrams of line display and dot display of spectrum display are...
