Summary of Chapter II 1.Data Transmission

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

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

Step 3 Coding with self-clocking (Manchester code)

Step 4: modulation (ASK)

Step 5: send over the channel

Step 6: Demodulation

Step 7: Decode

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

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

3. Probability: mean, variance, normal distribution
