Chapter 3- Transmission Principles

Noise

There are 4 categories of noise:

1. Thermal noise

2. Intermodulation noise

3. Crosstalk

4. Impulse noise

Routers are connected to each other. This is why they are called internetworking devices.

RSA Algorithm

1. Select two prime numbers, p=7 and q=17
2. Calculate n=pq = 7*17 = 119
3. Calculate f(n)=(p-1)(q-1) = 96
4. Select e such the e is relatively prime to f(n)=96 and less than f(n); in this case, e=5.
5. Determine d such that de= 1 mod 96 and d<96. The correct value is d=77, because 77*5 = 385 = 4*96+1.
