I am a freshman preparing for employment. I tried to fill out my self-introduction with only what I learned at school, but I felt like something was missing, so I looked for something, and this lecture caught my eye. At first, I was half-hearted and thought about it for a week, but now that I look back, I think it would have been better if I had paid for it sooner. At school, I only learned the subject and the practical training was simple, but this lecture is good because it gives you assignments related to how the subject is used and the field. I recommend this lecture to those who are going to work in a digital circuit-related field.
