Course Objectives:
- To give hands on experience to implement digital modulation techniques, active filters and TDM.
- To introduce the electronic components used in digital communication.
- To enrich on various encoders for digital transmission with minimum error.
Course Outcomes:
On completion of the course, the student will be able to:
- Build circuits to implement digital pulse modulator.
- Model various digital modulation techniques
- Develop circuits to implement sequence generator, channel coding and multiplexer
- Construct circuits to implement various active filters
Module 1:
- Construct a simple sampling circuit and observe the waveforms. 2. Reconstruct a sine wave from its samples
- Build a pulse code modulator circuit and observe the waveforms
- Develop a delta modulator and observe the input-output waveforms
Module 2:
- Model a Binary Amplitude Shift Keying (modulator & demodulator) and observe the input-output waveforms
- Model a Binary Frequency Shift Keying (modulator & demodulator) and observe the input-output waveforms
- Model a Binary Phase Shift Keying (modulator & demodulator) and observe the input-output waveforms
Module 3:
- Construct a two channel TDM circuit (Multiplexer and Demultiplexer) and observe the waveforms.
- Develop a Pseudo Random Binary Sequence(PRBS) generator and observe output
- Design and Construct an even parity code generator circuit to detect and correct error
Module 4:
- Construct an active first order low pass filter and plot its frequency response
- Construct an active first order high pass filter and plot its frequency response
- Construct an active band pass filter and plot its frequency response
- Open ended experiment.
Suggested Open Ended Projects
(Not for End Semester Examination but compulsory to be included in Continuous Internal Evaluation. Students can-do open-ended experiments as a group of 3-5. There is no duplication in experiments in between groups. This is mainly for the purpose of continuous internal evaluation and a score of 15 marks. Students should prepare a separate report on open ended experiment of their choice.)
- Simulation of filters using simulation software.
- Simulate the digital modulation scheme.
- Implement the Linear block code encoder and decoder using simulation software.
- Develop Convolution encoder using simulation software

Sample Questions
- Generate and demodulate an ASK signal such that
- When modulation input is at logic 1 level, ASK amplitude must be 4V and
- At logic 0 level, ASK amplitude must be 8V.
- Build a circuit to plot the frequency response of active first order band pass filter with bandwidth of 2 kHz and centre frequency of 10 kHz.
