Embodiment approach
[0089] Based on the above-mentioned embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation mode, the method for generating the above-mentioned sinusoidal signal also includes:
[0090] The mapping relationship between the sinusoidal function value at each sampling point of the preset sinusoidal signal and the corresponding sampling point is stored in the sinusoidal signal generator in the form of a table in advance.
[0091] In practical applications, in order to further increase the speed of the sinusoidal signal generator when generating the target sinusoidal signal, the mapping relationship between the sinusoidal function value of the preset sinusoidal signal at each sampling point and the corresponding sampling point can also be pre-set in the form The form of is stored in the sinusoidal signal generator.
[0092] It can be understood that, because the sine signal generator can retrieve the sine function value of th...
