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.…
Pulse Modulation: Pulse modulation may be used to transmit analog information, such as continuous speech or data. It is a system in which continuous waveforms are sampled at regular intervals.…
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…
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,…
Principles of Communication Systems: In a broad sense, the term Principles of Communication Systems refers to the sending, receiving and processing of information by electronic means. Communications started with wire…
Introduction to Digital Filtering: It has been seen that control of the band width of a circuit or signal is of paramount importance in optimizing the measurement of a signal.…
