A book about waves
I have written a book that teaches the basics of waves and signals. It is intended for people who never studied much maths at school or who find the subject difficult to understand. It starts at the very beginning with definitions of Sine and Cosine, and progresses from there. It would be useful for anyone who has bought a software defined radio and wants to learn enough to make the best use of it.

Generally, either maths books are intended for children, in which case, they are over-simplified and cover a very specific syllabus, or they are written for university maths students, in which case, they are written as if the reader were a mathematical genius. There are few books in between. My book is designed to teach anyone who wants to learn about waves, no matter what their ability. It goes into much more detail than most books. It is the book that I wish I had had when I first bought a software defined radio (and when I was at school). Although it is not intended to be a text book, it will help people struggling to learn maths academically.
