1. Design, implementation and studies of the properties of 15 bit P.N. Sequence using shift register.
2. Studies of the properties of A/D and D/A converter (AD7820/ADC0820 and ICL
8018A/8019A/8020A).
(Properties like transfer characteristics, code central line method of nonlinearity study, differential
nonlinearity, integral nonlinearity, resolution etc).
3. Study of pulse amplitude modulation and demodulation.
(Studies of distortion factor of the constructed signal as a function of signal frequency &
amplitude. Further study of distortion factor of filtered reconstructed signal as a function of
sampling frequency and thus verify the sampling theorem).
4. Studies of PCM transmitter and receiver.
(To measure the bit rate, bandwidth requirement and distortion factor of the reconstructed signal
in presence of channel noise).
5. Study of line coders: UPNRZ, PRZ, BPRZ, PNRZ
(To study the nature of waveform in CRO and its spectrum by spectrum analyzer. At least any
one of the line coders has to design, fabricated and tested).
6. Studies of Manchester coding and decoding technique.
(Studies of the nature of waveform, spectrum and self-synchronizing characteristic).
