Delta Modulation(DM): Delta modulation(DM) is process of modulation in which train of fixed width pulses is transmitted. Their polarity indicates whether the demodulator output should rise or fall at each…
Pulse Amplitude Modulation(PAM): Pulse Amplitude Modulation(PAM) is the simplest form of Pulse Modulation. It is shown in Fig. 18.7. PAM is a pulse modulation system in which the signal is…
Digital Memory Waveform Recorder (DWR): The Digital Memory Waveform Recorder (DWR) shown in Fig. 12.18, provides capability which is difficult to achieve by other methods. The block diagram (Fig. 12.18)…
