Chapter 4

Chapter 4. Digital Transmission. Example 1. A signal has two data levels with a pulse duration of 1 ms. We calculate the pulse rate and bit rate as follows:. Pulse Rate = 1/ 10 -3 = 1000 pulses/s Bit Rate = Pulse Rate x log 2 L = 1000 x log 2 2 = 1000 bps. Example 2.

According to the Nyquist theorem, the sampling rate must be

Note. According to the Nyquist theorem, the sampling rate must be at least 2 times the highest frequency contained in the signal. Figure 4.23 Nyquist sampling rate for low-pass and bandpass signals. Example 4.6.
