Communication Systems Practice Questions

Practice problems for Analog Communication Systems

Generate GATE-level questions on Digital Communication. Focus on: 1. Pulse Modulation: PCM, DPCM, Delta Modulation, and Adaptive Delta Modulation. 2. Digital Modulation Techniques: ASK, PSK, FSK, QPSK, and QAM. 3. Pulse Shaping: Matched Filter, Inter-Symbol Interference (ISI), and Nyquist Criterion. 4. Probability of Error: Calculations for various digital modulation schemes in AWGN.

Generate GATE-level questions on Information Theory and Coding. Focus on: 1. Information Measures: Entropy, Mutual Information, and Channel Capacity. 2. Source Coding: Shannon-Fano and Huffman coding theorems. 3. Error Control Coding: Linear Block Codes, Cyclic Codes, and Hamming Codes. 4. Channel Coding Theorem and Shannon-Hartley Law.

Generate GATE-level questions on Random Processes and Noise. Focus on: 1. Random Processes: Autocorrelation, Power Spectral Density, and WSS properties. 2. Filtered Random Processes: Response of LTI systems to random inputs. 3. White Noise and Gaussian Noise characteristics. 4. Random Variables: PDFs, Expectations, and Variance calculations.
