Summary of Chapter II 1.Data Transmission

2
Step 1: what we have Analog signal Carry wave (carrier) Received singal ??

3
Step 2 After sampling and quantization, we obtain = (three-level coding is applied)

4
Step 3 Coding with self-clocking (Manchester code)

5
Step 4: modulation (ASK)

6
Step 5: send over the channel

7
Step 6: Demodulation

8
Step 7: Decode

9
Step 8: Convert back to analog signals (assuming our sampling is fast enough)

10
2. Fourier transform (a light touch) Time domain Frequency domain

11
3. Probability: mean, variance, normal distribution
