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 Code Modulation(PCM): Pulse Code Modulation(PCM) is different from the other forms of pulse modulation studied so far, PCM also uses sampling techniques, but it differs from the others in…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
Pulse Time Modulation(PTM): In Pulse Time Modulation the signal is sampled in the same way as in PAM, but the pulses indicating instantaneous sample amplitudes have a constant amplitude themselves.…
Time Division Multiplexing(TDM): Time Division Multiplexing - Any pulse modulation scheme involves translating the audio, or modulating signal into a series of encoded pulses, sending these pulses over a transmission…
Digital Communication System: Digital Communication System has several distinct advantages over analog transmission systems, but there are definite disadvantages to it as well. Because of the heavy investment in analog…
Data Logger Summary: In general, a data logger is a comprehensive and highly advanced Data Logger Summary. It is made versatile and flexible, to render it suitable for widely varying…
Multi Channel Data Acquisition System: The Multi Channel Data Acquisition System can be time shared by two or more input sources. Depending on the desired properties of the multiplexed system,…
