Embodiment Construction
[0024] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0025] figure 2 A schematic diagram of the principle of the signal sampling testing method according to the first embodiment of the present invention is schematically shown.
[0026] The signal sampling test method according to the first embodiment of the present invention includes:
[0027] The first step: detecting the starting point T0 of the sinusoidal signal as the signal Fout to be sampled, so that the testing machine and the sinusoidal signal can be synchronized in timing.
[0028] Second step: using the testing machine to randomly generate a plurality of periodic pulse sampling signals (square wave signals), wherein each periodic pulse sampling signal in the plurality of periodic pulse sampling signals is generated separately, and The...
