After reviewing two online tutorial "analog sampling basics" and "basic analog circuits", I really want to complain the accent of the tutors.
As a foreigner who has leaned English as a second language and who does not live in a English speaking country, I have big difficulty to understand what they say. If it was a live training, I might be able to ask them to speak more clearly, but as for such webcast I couldn't do it.
Please understand that the most foreign engineers learn just "college English" with some standard accent like those spoken in CNN, you know what I mean. So this kind of accent is really unfamiliar to us. I have no doubt that the tutors are experts in their areas. But if NI wants to spread those knowledge to its customers, first it should make sure they can understand the English these experts speak.
