Sine to Silicon is my teaching channel. I explain the ideas behind digital signal processing, analogue and digital IC design and chip design in plain words, with everyday examples and animated pictures, starting from school maths. The first courses are DSP from Scratch and Optimisation from Scratch.
I run two small private tools for the channel: Sine to Silicon Stats (Google) and Sine to Silicon Publisher (Meta). They are used only by me, only on my own Sine to Silicon accounts, to read the channel's statistics, publish its posts and answer comments. They are not offered to anyone else. How they handle data is described in the privacy policy, and their use is governed by the terms of service. The YouTube tool uses YouTube API Services; see the YouTube Terms of Service.
