  1. Explain the need of modulation. Differentiate linear and non-linear modulation with mathematical equations.
  2. Describe the changes in FM spectrum, when deviation (f ), or modulating frequency ( f m) are changed, independently.
  3. With the help of block diagram, differentiate low-level modulation and high level modulation.
  4. Describe the working of Frequency converters and mixers with the help of circuit diagrams.
  5. Describe selectivity and sensitivity. How can they be plotted for a given receiver?
  6. Describe FM capture effect.
  7. An SSB transmission contains 10 kw. This transmission is to be replaced by a standard amplitude modulated single with the same power content. Determine the power content as the carries and each of the side bonds when the percent modulation is 70%.
  8. Describe sampling theorem. Write Interpolation formula. What is Aliasing?
  9. Write the practical values of Bandwidth, IF, and frequency deviation for AM & FM.
  10. Explain, why local oscillator frequency is kept higher than single frequency, and not vice-versa.
