Interpolation could help if you have enough samples. "Linear interpolation" from figures above is the simplest but with sin(x) and cos(x) is better. May be the following papers will help to understand better the topic: 1. "ET 4 CO 198.pmd", www.ieindia.org/pdf/88/88ET104.pdf 2. "9 CP PE 8.pmd", www.ieindia.org/pdf/89/89CP109.pdf 3.

This technique was used in data or signal compression technology, right? Short explanation but very clear, Thanks. This technique was used in data or signal compression technology, right?
