EC51-DIGITAL COMMUNICATION UNIT-1 DIGITAL COMMUNICATION SYSTEM 1. What are the advantages of digital transmission? The advantage of digital transmission over analog transmission is noise immunity. Digital pulses are less susceptible than analog signals to variations caused by noise. Digital signals are better suited to processing and multiplexing than analog signals. Digital transmission systems are more noise resistant than the analog transmission systems. Digital systems are better suited to evaluate

OBSERVATION The modicom 1 board‚ first in my observation is the power input these are the electrical input connections necessary to power the module. The LJ Technical Systems’ "I.C. Power 60" or "System Power 90" is the recommended power supplies. Then second is the sampling control logic is the circuitry generates the timing and control signals that sample the input waveform‚ and also creates a sinusoidal 1 kHz signal for use during the MODICOM 1 practical exercises. It is recommended that this

DIGITAL SPEEDOMETER NARENDRA WADHWANI T his instrument displays the speed of the vehicle in kmph. An opaque disc is mounted on the spindle attached to the front wheel of the vehicle. The disc has ten equidistant holes on its periphery. On one side of the disc an infrared LED is fixed and on the opposite side of the disc‚ in line with the IR LED‚ a phototransistor is mounted. IC LM324 is wired as a comparator. When a hole appears between the IR LED and phototransistor‚ the phototransistor
