CONTENTS:

• Digital communication system model
  
• signals
  
• classification of signals: analog and digital signal, continous time and discrete signal and all classification of signal
  
• properties of signal. include: Amplitude, frequency, phase, wavelength, time period
  
• relation btwn lemda, t and f
  
• phase
  
• some standard signal use in signal analysis include: unit step, impulse, signum function, ram function.
  
• effect of limited bandwith
  
• find transform unit F(t) of impulse signal, step signal, ram signal
  
• properties of F(t) transform
  
• ESD energy spectral density and PSD power spectrum density.
  

this covers full syllabus of section a of mdu btech and some other universities please recheck topics in your university syllabus

note; if this is  helpful for you then dont forget to help other students by posting some more useful stuff here.
