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
