Solution
For solving question 1, please refer to the article Data Conversions and Encoding Techniques
All data conversion types and encoding techniques are categorized and listed in the article.
Question No. 2 Solution
For calculating baud rate, see the following example from CS601 Data Communication handouts, Page 93
Example:
A constellation diagram consists of eight equally spaced points on a circle. If bit rate is
4800 bps, what is the Baud Rate?
Solution:
Constellation indicates 8 PSK with the points 45 degree apart
Baud Rate= 4800 / 3 = 1600 baud
