IETE DIPIETE-ET (New Scheme) Digital Communications Papers are based on topics which are related to the paper. The questions are both of the short answer objective type and the long answer type. Topics from which questions are likely to come include Huffman encoding, Time Division Multiplexing, the important of Sampling Theorem and Nyquist Rate, the role of Nyquist interval in digital communication, the diagrammatic aspects of the Pulse Code Modulation, the differences between the NRZ Polar and NRZ Bipolar formats, the role of Inter symbol interference. Diagram based questions can also be expected from topics like QPSK system. IETE DIPIETE-ET(New Scheme) Digital Communications Papers also include topics like matched filter and its impulse response, Frequency HOP Spread Spectrum, slow frequency hopping, Gram-Schmidt orthogonalization and so on. The objective questions are generally in the MCQ format and can be quite high scoring if the student’s are aware of the concepts.
