Position of pulses varies with the signal.
In the world of Electronics and Communication Engineering, few subjects are as foundational—or as challenging—as Communication Systems. Whether you are preparing for university exams, GATE, or simply trying to grasp the concepts of signal transmission, having the right resource is half the battle won.
Unlike heavy, theory-laden Western textbooks (like Proakis or Haykin), Sanjay Sharma’s approach is tailored to the undergraduate curriculum of Indian universities (VTU, JNTU, Anna University, UPTU, etc.). Here is why it remains a favorite:

Digital transmission offers higher noise immunity and security compared to analog. This section focuses on transmitting data over physical channels.
The book covers both classical analog systems (AM, FM, Superheterodyne receivers) and modern digital systems (PCM, ASK, FSK, PSK, QPSK, Spread Spectrum). It even touches on optical fiber and satellite communication in later editions.
Analog communication transmits continuous signals. Dr. Sanjay Sharma’s book breaks this down into two main types of modulation: Amplitude Modulation (AM) and Angle Modulation (FM/PM). Amplitude Modulation (AM) a section on the author
